Description

The utility model relates to heating equipment, namely to heat exchangers operating on solid fuel, which can be used for heating residential and other premises, as well as for hot water supply. As solid fuel, for example, coal, sawdust, peat, pieces of wood, a mixture of these types of fuel, etc. can be used.

Known heating boiler, in which there is a furnace with grates, a convection part, a water jacket, means for supplying an oxidizing agent. The convention part is located above the stove and contains water pipes in which water is heated by the products of fuel combustion from the stove (Ukrainian patent for invention No. 56752).

The disadvantage of the analogue is the relatively large percentage of unfinished fuel, especially with a high moisture content and high ash content, which increases the cost of heating, and the need for a constant supply of fuel, since the duration of burning of one of its load is not long.

Also known is the “Stropuva long-burning solid fuel boiler”, which contains two steel cylinders (one inside the other) with water in the space between them and the stove inside the small cylinder (Internet site http://www.stropuva.org/). The design of the boiler provides a long burning process (on one tab 5-30 days) in the upper layer of the fuel filling, which complicates the process of ash removal, which in turn affects the quality of combustion.

The KVR-50K Teplotron heating solid heating boiler, which contains a housing consisting of an external and an internal heat exchanger tanks, the space between which is filled with coolant and the last of which has a loading hole, a furnace with a grate and an ash pan (Internet site of the company LLC Rusteplosistemy http://www.kotel-nk.ru/company/).

The disadvantage of this design is non-efficient 4) efficient combustion of fuel and a small furnace volume, which leads to the need for frequent loading of fuel.

The utility model is based on the task in the known design of a solid fuel boiler to increase the efficiency of fuel combustion and, accordingly, the efficiency of the boiler, while increasing the duration of combustion of one fuel load due to the use of flue ducts from the ejection channels in the boiler design.

The task is achieved by the fact that in the solid fuel boiler of super-long burning “Energy TT”, containing a housing consisting of external and internal tanks of the heat exchanger, the space between which is filled with coolant and in the last of which there is a loading hole, a furnace with a grate and an ash pan, in the inner at least one gas duct is installed in the tank, the intake part of which is connected through an opening to the air intake and through the ejection channel to the lower part of the furnace, and the output part is led out to the upper of the furnace.

In another specific execution speed, according to a utility model, four gas ducts with ejection channels are symmetrically placed in the inner tank.

In another specific embodiment, according to a utility model, upper and lower ash doors are installed in the housing relative to the grate.

The above mentioned new features (gas duct from the ejection channel connecting the air intake and the lower part of the furnace to the upper) when interacting with known signs (body, heat exchanger tanks, coolant, loading hole, furnace with a grate and ash pan) provide the identification of new technical properties of the utility model and obtaining a technical result - increasing the efficiency of the boiler, while increasing the duration of combustion of one fuel load. Ultimately, it was possible to improve the consumer properties of the system associated with the technical result, namely: ease of use due to the reduction of interruptions in the operation of the boiler for its maintenance during the heating season.

The drawing shows a structural and technological diagram of a solid fuel boiler superlong burning "Energy TT".

The solid fuel boiler of super-long burning “Energy TT” contains a housing 1, consisting of external 2 and internal 3 metal tanks of the heat exchanger 4, the space between which is filled with coolant (water) 5, which is supplied and discharged through pipes 6 and 7. In the internal tank 3 there are loading a hole 8, a stove 9 with a grate 10, which simultaneously serves as a loading hopper, an ash pan 11 of the upper 12 and lower 13 ash doors and gas ducts 14 of the mixing chambers 15. The intake part 16 of the gas duct 14 is connected to Through the hole 17 with the air intake 18 and through the ejection channel 19 - with the lower part 20 of the furnace 9, and the output part 21 is displayed in the upper part 22 of the furnace 9, where the pipe 23 for the exit of combustion products of solid fuel 24 is installed.

The diagram shows the flows of air and dimogas: the first part of air 25, the second part of air 26, additional air 27, dimogaz 28 and a mixture of dimogaz with the first part of air 29.

Solid fuel boiler superlong burning "Energy TT" is used as follows.

Through pipes 6 and 7, the boiler is connected to the heating system. Using the loading hole 8, solid fuel 24 is loaded into the furnace 9 to its upper part 22. The fuel combustion zone, for example, coal, is the lower part 20 of the furnace 9. A layer of ash accumulates on the grate 10 from coal combustion, which serves as some resistance and separates the input air flow in two. The first part 25 of the air stream is sent to the flues 14, taking with them dimogas 28 and unburned oxygen directly from the combustion zone through the ejection channels 19. The second part of the stream 26 passes through a layer of ash formed from the burned coal and is located on the grate 10, to the burning center , provides the process of fuel oxidation in it. Additional air 27 is also supplied to the flues 14 through the ejection channel 19, which creates an ejection effect, enhances the capture of dimogas 28 and forms the composition of the combustible mixture in the mixing chambers 15, where it is burned.

The released heat energy from the oxidation process of the fuel 24 passes through the heat exchange walls of the inner tank 3 and the flow grate 10 to the heating system (hot water supply).

The use in the design of the boiler gas ducts 14 with ejection channels 19 provides:

1) capture of dimogas directly from the combustion zone, which is carried out by the air flow to prevent its attenuation due to their accumulation and their directing into the flues through the ejection channels and into the mixing chambers for burning the formed air-gas mixture in them;

2) the capture of excess oxygen directly from the combustion zone passes through the air stream to prevent its arbitrary combustion and direct them into the flues through the ejection channels and into the mixing chambers for burning the resulting air-gas mixture in them;

3) mixing the components coming from the combustion zone with additional air, which is supplied to burn the resulting mixture.

The advantage of this utility model is that during operation of the solid fuel burning boiler, it is possible in an inexpensive way to obtain a wide range of regulation of the thermal power of the boiler without a significant decrease in efficiency and to distribute the heat transfer of the loaded coal mass for an extra long time without human intervention and without the use of additional mechanisms fuel supply and shaking the grate to release ash in the combustion zone. As a result, the consumer receives a device for providing thermal energy that does not require maintenance for an extra long time, as far as the total calorific value of the loaded fuel mass at a time allows, until that time, no known design of solid fuel boilers has been implemented. For use by the population, based on the acceptable size of the boiler for most rooms, it is possible to realize the burning time of one coal laying up to 45 days without human intervention.
