At first glance, a plurality of welded thin deformed rectangular plate heat induction plates and flame induction outer ring conical rods installed in the furnace were installed, oxygen was sent by blowing from the bottom of the ash tray in the furnace, and the flame The amount and speed of this can be greatly improved. The two split semi-cylindrical types are perforated on the thin double pipe side and the water tank side, and water flow bypasses and pipes are installed outside, circulating hot water. And make it possible Since it is suitable for burning all kinds of biomass fuel, there is no small flame or water pipe in the furnace, so there is no breakage or deterioration, long-term stable use and maintenance with a split boiler, easy steam generation time The present invention relates to a split boiler type biomass steam power generation method characterized by a compact structure.

On the earth, at present, the use of biomass energy is not used on an average of 10% of the total energy requirement, whether it is for industrial use or for daily use throughout the world.
In recent years, biofuels have been reviewed, especially due to rising oil prices, mainly in large agricultural areas in the United States, Australia and Brazil, turning food into ethanol raw materials and increasing biofuel production. The shortage is considered a problem and the price rises. Also, due to a major accident at the nuclear power plant caused by the Tohoku earthquake on March 11, 2011, it was considered difficult to install a new nuclear power generator. Development of boiler-type generators is required.

Three times the heat energy that human beings need to live on the earth naturally grow, including non-food wood, bamboo, weeds, edible plant waste, and architectural waste. If we can develop a system that can stably use boiler hot water hot water supply and use power generation enough to build a recycling system for biomass energy that can be used in each region, There is no need to use it. Wind power and solar power generation need only be used supplementarily, and development is also urgently required to prevent global warming by establishing clean energy together with small and medium hydropower generators.

Conventionally, large-scale thermal power generators installed and operated by large power companies have been the mainstream as steam boiler generators. Recently, a generator that mainly collects raw garbage and pellets and burns it has been developed and operated, and at the same time, a facility is being built that also uses a boiler and hot water hot water.

However, the above-mentioned garbage boilers, hot water hot water supply and generators are also basically required to increase power generation efficiency, and further to reduce the cost of equipment,
(B) Large capital is required to increase the size of one machine.
(B) Difficulty in selecting the installation location due to the increase in size.
(C) There is a need to collect garbage from a wide area. Recently, the distance from the consumption area to the power plant has been seen as a problem by wide-area municipalities, and the amount of garbage brought into the power plant has been greatly reduced due to the reduction in the amount of garbage in the district. It has become less. The power generation incineration and hot water hot water supply capacity have been greatly reduced.

For this reason, it is difficult to maintain large-scale garbage power plants. On the other hand, instead of incinerating raw garbage in local municipalities, conversion to fertilizer or feed is also an important factor in the amount of garbage brought into incineration. It also contributes to the decline.

Most of the conventional garbage incineration power plants are heated to high temperature and downsized power generation facilities, so this garbage is heated with high heat, dried quickly and fixed to a certain size and weight (also called RDF) It has been converted into a biomass fuel called) and then put into incinerators for power generation and hot water hot water.

This biofuel pellet is hard and heat efficient, and has advantages such as downsizing of the equipment, a small number of managers, and easy long-term use control such as unmanned operation.

However, the disadvantages of this pellet fuel generator and hot water heater are:
(B) Equipment costs and personnel costs for pelletization are required, resulting in high costs.
(B) Hard materials such as timber and bamboo are hardly available due to the use of soft bio-friendly materials that are relatively easy to pelletize, such as garbage and grass.

Furthermore, the pellets are standardized to a certain amount and size, and the advantages such as easy incineration are the same as described above. However, the size of hard and large items such as wood and bamboo, and incineration materials such as construction waste However, it is not always possible to use irregular materials, and it is necessary to reprocess the pellet material, which is expensive, and due to the large size of the equipment, it is often difficult to install a processing plant for pellets, a generator and a hot water supply near the consumption areas in each region. It is necessary to develop a small device that mainly uses generator equipment.

These are not conventional large biofuel generators and boiler water heaters,
(B) Equipment that can be incinerated with cuts of 20-30 cm, such as forest thinning, bamboo, building waste, etc.
(B) Incineration of chips and pellets (roughly cut to 2 to 3 centimeters), including grass, rice husk, sawdust, garbage, bamboo and wood,
(C) The entire equipment is small, has little space and can be easily installed near the consumption area, and the investment can be made with a small amount.

    (D) In addition, it is an efficient power generation and hot water heater that does not require a water softener and is easy to install, perform periodic inspections, and maintain, and can be used in developed countries, developed countries, etc., especially in highland mountains. That is.

The development of a machine that cleans the flue gas described above requires a small-sized device that can use hot water hot water supply and power generation using biomass energy throughout the year in the consuming area, and is said to emit CO2 in flue gas during incineration. However, if biomass also has a combustion temperature of 700 ° C or higher, dioxin generation is greatly reduced. In Europe, biomass supplies oxygen as it grows, and this is used as energy. The emission rate is calculated as 0% deduction, and it is necessary to relax emission regulations in Japan.

JP 2006-307655 A JP 2012-202401 A Japanese Patent Laid-Open No. 2002-39048 In these patent applications, most of the applications using hydropower are for solar and gas combined use, tap water, flush toilets, etc. There is still little development of a compact size generator with biomass water heater that can be incinerated.

The present invention is intended to solve the problems of such conventional methods and configurations, and provides a method for a hot water combined bio-generator device that is small, inexpensive, and has good combustion efficiency. It is aimed at.

The problem we are trying to solve is
(B) With conventional smoke tube boilers and once-through boilers, various biomass fuel boilers are quickly attached to soot and water pipes and oily soot, which reduces the efficiency of steam generation as a boiler. Is it possible to develop a boiler different from the conventional one because the entire furnace is aging quickly?
(B) How can the boiler temperature rise quickly and produce a large amount of steam? Is there a method that is easy to manufacture, install, maintain, and manage?
(C) I want to use biomass water heaters and generators in mountainous villages where there is a lot of thinned wood. Isn't it possible to reduce the initial investment in production and make a compact device that can be used in an efficient greenhouse or home?
(D) Isn't there an automatic device that can incinerate biomass with a lot of black smoke, such as cedar, pine, bamboo forest, etc., as fuel by cutting logs and squares of appropriate size?

A power generation method can be provided.

Inventive action is as follows. In the first invention, since there is no flame feed pipe or water circulation in the furnace, and there is no small pipe at all, so there is a lot of soot such as wood, especially pine, bamboo, etc. Completed a boiler with high oil content and capable of burning high temperature materials, grass plants, etc., using air blow as a biomass combustion boiler, the temperature of the flame rises in the burner state, the flame hits the entire outer periphery of the furnace, and the bottom of the boiler is made thin The effect of generating steam in a short time was confirmed.

Of the action of the second invention,
(A) Steam is generated when the water in the boiler tank boils from hot water. This is called saturated steam. This steam is returned to the boiler furnace with a flexible pipe to reheat and reheat to dry steam. Therefore, a turbine capable of radiating through a nozzle to a steam turbine as sufficient dry steam with low moisture content is from 3,500 times / minute of saturated steam to 7,000 to 8,000 / minute of dry steam and a turbine having a diameter of 170 mm. The action of high-speed rotation worked, and steam energy could be used most efficiently.

In the second invention, (B), the condenser rotates the steam turbine by discharging high-pressure steam with a steam nozzle, and the steam is at a high temperature of 170 to 200 degrees and discharges steam to the condenser. The cooling system is used to cool the steam by passing multiple cooling flexible pipes inside the condenser and passing cold water through the pipes. The cold water pipe is also several tens to several meters outside the condenser. Winding 100 meters to cool the water in the flexible pipe, so the high-temperature steam in the condenser can be cooled and adjusted to 70 to 80 degrees and pumped again into the boiler with a high-pressure pump. Can be made from double to triple, the outside is the role of heat retention and the role of boiling the hot water, depending on the area, this hot water becomes a high temperature from 70 degrees to 80 degrees, and the action to make the hot water was confirmed.

(C) Opening the bottom of the boiler furnace of the second invention action, making incineration ash of radioactive pollutants by ash falling into the inner box by making a double box under the burning ash falling Processing was possible without touching the hand, and the exhaust gas was able to decontaminate more than 90% by installing a decontamination filter in the middle of the chimney.

The third aspect of the invention is that the flame backflow preventer from the combustion furnace is equipped with an automatic feeder for pellets and chips so that the boiler can be automated for 10 hours of continuous combustion and pellets, chips, wood, bamboo, grass plants, etc. are not aligned. Biomass combustion is possible with a single boiler, and when the boiler is manufactured, a cleaning brush is inserted into the boiler, or the brush can be replaced later, and there is no need to soften the boiler water. To make it clear, the cup-type water supply double filter was passed, so that even mud water containing muddy water passed through the same filter and became the boiler water.

The above-described split boiler type biomass steam generator of the present invention exhibits the following effects.

The effect of the first invention was a sufficient steam generation effect as the third boiler without using the conventional boiler flue pipe type (1) and the once-through type (2).
Whether it is a generator or a boiler water heater, it depends on the efficiency of the entire boiler and has the following effects.
(B) The whole is easy to manufacture.
(B) A high temperature rise rate can be reached quickly by burning a small amount of biomass.
(C) Especially for pine and bamboo, black smoke is generated and soot is generated in the furnace, so the heat efficiency is reduced, and early cleaning of the furnace is necessary. However, the boiler furnace can be divided in half and directly Stainless steel and rotating brushes can be used in the furnace, making it easy to check for other steam leaks, and the same boiler can be used for a long time.

In the second invention effect, in conjunction with the action of the first invention, the steam of the boiler is collected in a steam reservoir, this steam becomes saturated steam, and this is heat-resistant and high-temperature flexible pipe, which is swirled several times in the furnace. Rotating and reheating further reduces moisture, radiates from the nozzle to the steam turbine, and the 170mm diameter turbine depends on the nozzle diameter, but it rotates 8,000-9,000 without load and slows down sufficiently The effect of rotating power generation with a load on the generator was achieved. The conventional steam turbine rotates by 2 to 30,000 with the same size, but the steam turbine of the present application rotates by increasing the radiation pair pressure from the nozzle by 2 to 3 times by making the steam blade specially made. The force was increased, and the effect of the force to sufficiently rotate the generator occurred.

Part 2 of the operation of the second invention is that the condenser is related to the effect of saving water through the circulation of boiler water and the pumping of hot water to stabilize the temperature in the boiler to stabilize the amount of steam. Is also effective.

Further, the third effect of the second invention function is a triple pipe as a whole, the inside is the boiler section, the outside is the inside boiler heat retention and the outside warm water can be used for warm water such as for greenhouses. The effect can be confirmed, and the treatment of incineration ash also has the effect of treating the radioactivity and chemical-containing ash without touching them by double the incineration ash receiving box.

The effects of the third aspect of the invention are as follows: (1) The biomass steam generator is also equipped with a flame flow preventer for the furnace, and an automatic biomass feed device is provided to enable automatic operation of the boiler. (2) In the boiler By inserting a cleaning brush and a rotating brush at the time of manufacture, it becomes possible to clean the inside of the boiler when necessary. Sludge water is passed through a double filter to make it transparent and maintain boiler efficiency and deteriorate the boiler. The effect of not using the water softener, which is expensive, expensive, and complicated in electrical control.

The effect (3) of the third invention is that the automatic device of the biomass steam generator is made compact with a split boiler combining the first invention product, the second invention product, the third invention product, non-use of water softener, etc. Produced as a set and can be used in combination with power generation and hot water, it has the effect of expanding the range of use of biomass power generation methods such as developed countries, underdeveloped countries, mountains, and remote islands.

As mentioned above, one conventional biomass steam generator is fixed, large equipment is the mainstream, and it has a separate structure from the pellet processing machine, generator, and hot water heater. Since it is brought in from various places and mainly used as RDF (solidified) for household garbage, the building is large, the installation location is limited, and the spread of biomass power generation has been delayed.
The invention of this application is based on the data that failed to make a prototype of a large and small boiler 8 times, the steam blade failed 50 times, the boiler succeeded the seventh time, and the blade successfully tested the 51st time. In addition, pellets, chips, logs, squares, weeds and other structures that can be incinerated even if they are not uniform in size are combined into a single unit, and the amount of steam, hot water, and power generation is less than that of fixed large facilities, but where biomass fuel is present and vinyl Steam, hot water, and methods for lighting power generation , production, installation and maintenance are easy and easy to use and spread in houses, vegetable house factories, industrial waste disposal companies, etc.
