Abstract
The utility model discloses a steam boiler used for the mixed firing of residential wastes and pulverized coals, which belongs to a steam boiler and particularly relates to a pulverized coal steam boiler with the function of residential waste incineration. The steam boiler comprises a hopper (1) and a waste incineration boiler (2), and further comprises a micro-oil igniting pulverized-coal burner (3) and a fan mill (4). The utility model provides an ideal steam boiler which is used for the mixed firing of residential wastes and pulverized coals and can ensure continuous and stable burning of the residential wastes, thorough incineration of wastes, full disassociation of hazardous materials, radical burning of organic matters, and complete release of heat energy. By additionally arranging the fan mill (4) and the micro-oil igniting pulverized-coal burner (3), the mixed firing of the residential wastes and the pulverized coals is realized, and the temperature of a furnace chamber is equal to or greater than 1000 degrees C, so that, high and stable temperature of the furnace chamber is ensured. The steam boiler has the advantages of energy conservation, environment protection, simple structure, low manufacturing cost, simple and convenient operating technology, stable operation, low production cost, and good economic benefit.
Description
Technical field
The utility model is a kind of house refuse and coal dust multifuel combustion steam boiler, belongs to steam boiler.Be particularly related to the coal dust steam boiler that has the consumer waste incineration function concurrently.
Background technology
The minimizing of house refuse, innoxious and recycling treatment are the targets that people are striving for always.Because in burning disposal, can obtain the heat energy of human lives and the needed preciousness of development, but house refuse itself has the complex structure of composition and constantly changes the moisture content height, the characteristics that calorific value is lower, it is very difficult reaching desirable burning effect.Though make great efforts untiringly through the insider, burning facility is updated, following problem still has to be solved:
1. domestic waste incineration of the prior art, the mechanical air supply of employing, grate firing mode, fire box temperature are difficult to improve, cause to guarantee that house refuse continues, smooth combustion, be difficult to reach and incinerate thorough minimizing, decompose innoxious fully, the purpose of organic after-flame resource.
2. furnace temperature is difficult to surpass 900 ℃, causes in the waste incineration process, and harmful components such as dioxin can not be decomposed fully, cause second environmental pollution.
3. need dispose pretreatment unit, igniter and auxiliary combustion equipments such as drying separately, complex structure, manufacturing cost height, operating procedure complexity, fluctuation of service, production cost height.Deficiency in economic performance.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, guarantee that house refuse continues, smooth combustion and provide a kind of, the incineration of garbage is thorough, harmful substance is decomposed fully, organic matter burns, and simple in structure, low cost of manufacture, operating procedure is easy, and is stable, production cost is low.Good in economic efficiency, energy savings helps the ideal life rubbish and the coal dust multifuel combustion steam boiler of environmental protection.
The purpose of this utility model can reach by following measure:
House refuse of the present utility model and coal dust multifuel combustion steam boiler comprise hopper 1, and garbage burning boiler 2 is characterized in that also comprising micro-oil ignition coal powder combusting device 3 and blower mill 4.
By setting up blower mill 4 and micro-oil ignition coal powder combusting device 3, realize house refuse and coal dust mixed combustion, thereby guarantee the fire box temperature height and stablize.
The key equipment of middle-size and small-size pulverized-coal fired boiler is applied to the consumer waste incineration system, rubbish is surely fired, fire box temperature 〉=1000 ℃.Simplified the rubbish pretreatment system, the consumer waste incineration system is moved continually and steadily.The inventor on former life garbage burning boiler basis, increases blower mill and two micro-oil ignition coal powder combusting devices by test of many times, and micro-oil ignition coal powder combusting device can effectively be regulated fire box temperature according to refuse thermal value in more high-power scope.House refuse and coal dust multifuel combustion steam boiler are organically blending of two kinds of mature technologies, and it improves the adaptability of burning boiler to rubbish, have reduced the operating cost of boiler, have guaranteed the continual and steady operation of burning boiler, have comparatively vast market prospect.
House refuse of the present utility model and the disclosed technical scheme of coal dust multifuel combustion steam boiler have outstanding characteristics and significant technological progress compared to existing technology, and can produce following good effect:
1. provide a kind of and guaranteed that house refuse continues, smooth combustion, the incineration of garbage is thorough, and harmful substance is decomposed fully, and organic matter burns, ideal life rubbish that heat energy discharges fully and coal dust multifuel combustion steam boiler.
2. by setting up blower mill 4 and micro-oil ignition coal powder combusting device 3, realize house refuse and coal dust mixed combustion, fire box temperature 〉=1000 ℃, thus guarantee the fire box temperature height and stablize.
3. energy savings is protected environment.
4. simple in structure, low cost of manufacture, operating procedure is easy, and is stable, production cost is low.Good in economic efficiency.

Embodiment 1
House refuse of the present utility model and coal dust multifuel combustion steam boiler, a preferred scheme comprises hopper 1, garbage burning boiler 2 also comprises two micro-oil ignition coal powder combusting devices 3 and blower mill 4.
Fire box temperature 〉=1000 ℃.Simplified the rubbish pretreatment system, the consumer waste incineration system is moved continually and steadily.On former life garbage burning boiler basis, increase blower mill and two micro-oil ignition coal powder combusting devices, little oil burner can effectively be regulated fire box temperature according to refuse thermal value in more high-power scope, improved the adaptability of burning boiler, reduced the operating cost of boiler rubbish.
