Description
Technical field
The invention belongs to new energy source energy-saving field, relate in particular to a kind of energy-saving biomass fuel boiler.
Background technology
Biomass boiler is a kind of boiler, be exactly with biomass energy as the boiler of fuel biomass boiler, be divided into biomass steam boiler, biomass hot water boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical type biomass boiler, horizontal biomass boiler etc.
Pressurization methods in biomass boiler heating system: in high-temperature-hot-water feed system, because water temperature is higher than water saturation temperature under normal pressure, thereby pressure should be adhered to the saturation pressure higher than corresponding supply water temperature in system, can avoid like this hot water vaporization and outbreak water slug. Water is the fluid that can not tighten, will step-down once leak out; On the contrary, water heating again can volume contraction, if can not steady pressure, also can damage the equipment in heating system. Thus, boost for fear of step-down vaporization and contraction, the pressure in the essential systems stabilisation of high temperature water heating system, level pressure that Here it is. The pressurization methods of hot-water heating system has following several:
1), adopt elevated tank pressurization methods
The pressurization point of this mode is located on hot water circuit pump intake or backwater backbone, and installing is only an elevated tank, its simple structure, working stability is firm, can systems stabilisation pressure, and can meet spilling water and the moisturizing request of grid. In this system, cistern device height must meet the unvaporized request of peak in system that makes. Thereby setting position is higher. This pressurization methods is suitable in the low-temperature water heating system little with heating range.
2), adopt pressurization by make-up water pump mode
When heating system pressure is higher, adopt senior water tank can not ensure the pressure that system is required, now, should adopt pressurization by make-up water pump mode. This pressurization methods is generally applied in Soviet Union's hot-water boiler heating system. Pressurization by make-up water pump has continuous water-supply and pressure-stabling and continuous two kinds of modes of water-supply and pressure-stabling. The installation of this biomass boiler pressurization methods is by extra feed tank, make-up pump, the compositions such as pressure conditioner. In the time that system works well, make the continuous moisturizing of make-up pump and make it to comply with mutually with the leakage quantity of walking of system through the conditioning of excess pressure conditioner, thereby maintain the stable of system pressure. In the time that water circulating pump is stopped transport, the stop valve before can closing presure conditioner. Make-up pump still continuously moisturizing to maintain the required static pressure of system. This pressurization methods is without shrinking water tank, and therefore cost of equipment is cheap, in addition, make-up pump not only moisturizing but also level pressure, pump power is little, and running expense is also very little. Thereby this mode is applied quite general in China's hot-water heating system. If the defect of this pressurization methods maximum is system while suddenly having a power failure, make-up pump will lose level pressure effect. For avoiding now boiler water shortage vaporization, in system, adopt water auxiliary type on pressure to install, in the time that water circulating pump turns round, to install because upper water is auxiliary, recirculated water can not pour in down a chimney in pressure rise system. Make water circulating pump when suddenly having a power failure, when make-up pump is stopped transport, pressure water-feeding system puts into operation at once, and check-valves is opened automatically, will flow through hot-water boiler discharging from air collector of press water, thus prevent that furnace chamber waste heat from incurring a pot water vapor. Operation is meanwhile close confession, and backheat water pipe main valve completely cuts off thermal source and heat supply network and comes. Biomass boiler pressurization by continuously running make-up water is completed by electro connecting pressure gauge control, water circulating pump inlet pressure can be maintained within a certain range, when pressure is during lower than this scope, electro connecting pressure gauge moves and connects make-up pump motor circuit, make-up pump running, moisturizing, when hot water circuit pump inlet pressure raises and surmounts certain limit, the Pressure gauge of hot-water boiler cuts off make-up pump power supply exactly, is that make-up pump is stopped transport. Action and so forth, the continuous moisturizing of make-up pump, and maintain system pressure and shake within the specific limits, steady of system press mode like this, due to continuous moisturizing, just than the economical electric energy of continuous moisturizing, but its conditioning and the continuous water supplementing method of level pressure mass ratio are poor, also have pressure to shake greatly, the Pressure gauge contact defects such as being easy to damage that acts frequently.
Biomass energy particle fuel is the crops that utilize all wastes such as stalk, paddy rice stalk, yule logs, wood chip, peanut shell, melon seed cases, beet pulp, bark, through being pulverized and mixed the techniques such as extruding oven dry, last granulation shape fuel. In China, its raw material are widely distributed, processing technology advanced person, and biomass energy particle material is famous with green coal, is a kind of clear energy sources. As the fuel of boiler, its burning time is long, and overheavy firing fire box temperature is high, and economical and practical, simultaneously to environment without any pollution, CO zero-emission, SO zero-emission, belong to the renewable sources of energy, reusable edible, can replace timber, coal, natural gas. And operating cost is only the half of combustion gas. The raw material that a large amount of agricultural of China produces provides strong material guarantee to the popularization of biomass boiler. Not only can solve peasant and carry out crop straw burning problem, resource be made full use of simultaneously, the lime-ash burning is extraordinary fertilizer, is to achieve many things at one stroke in fact.
