Description

The biomass burning hot-water boiler

Technical field

The invention belongs to the utilization of regenerative energy equipment technical field, be specifically related to a kind of biomass burning hot-water boiler.

Background technology

Along with coal, oil, Gas Prices rise steadily and reserves descend, shortage of energy sources and environmental pollution serious day by day, people begin to seek the new energy and replace traditional energy.It is found that afterwards that biomass energy was as a kind of energy of reproducible utilization, resource is very abundant, and has the low characteristics of phosphorus content, in its growth course, absorbs a large amount of carbon dioxide so be called as clean energy resource in addition.At present, the research and development of biomass energy is very fast, and the utilization of various new technologies such as gasification, pyrolysis, liquefaction, fermentation has all obtained bigger progress in succession.Because national industrial policies are to the attention of environmental protection, so exploitation biomass fuel equipment brings fair margin of profit can for a lot of producers, some producers are the biological substance for combustion shaped fuel; Do not understanding under the situation of its characteristic; Original fire coal or oil, the direct biomass burning shaped fuel of gas firing equipment, cause combustion space, shape and the biomass molding fuel burning of combustion apparatus not to match blindly, boiler heating surface and biomass molding fuel do not match; Excess air coefficient and biomass molding fuel burning do not match; Flue gas resistance is big, causes that the efficiency of combustion of boiler and the thermal efficiency are lower, the original discharge concentration of boiler smoke is high, and pollutant emission exceeds standard; And complex process, cost is higher.

Summary of the invention

The technical problem that the present invention will solve is, to the defective of prior art, a kind of biomass burning hot-water boiler is provided, and produces hot water behind this boiler biomass energy direct combustion capable of using, satisfies the needs of daily lifes such as people's warming by air conditioner usefulness.

Technical solution of the present invention is that said this biomass burning hot-water boiler comprises combustion stove and microscler pot body; It is cylindric that combustion stove is vertically-arranged, and the microscler pot body of an end band semicolumn end socket laterally places combustion stove on one side, and end joins with combustion stove integral body in addition; Said combustion stove bottom is provided with rotary fire grate, and the middle part is provided with combustion chamber and feed inlet, and top is provided with the fire tube and time smoke-box of many arrangements; The two ends of fire tube connect the combustion chamber respectively and return smoke-box; Said microscler pot chamber body is provided with many backhauls fire tube heat exchanger, and the bending tubes end of many backhauls fire tube heat exchanger communicates with returning smoke-box, and the smoke evacuation end of many backhauls fire tube heat exchanger connects air-introduced machine; The appearance of the last appearance of said combustion chamber, the appearance of fire tube, the appearance of returning smoke-box and many backhauls fire tube heat exchanger constitutes a heating water tank space with combustion stove and microscler pot body inboard jointly together; The water inlet interface that communicates with outer room is arranged at the top in the heating water tank space of microscler pot body end part; Following bottom side is provided with sewage draining exit; The water outlet interface that communicates with outer room is arranged at the top in the heating water tank space of combustion stove part.

In order to improve operational efficiency, above-mentioned many backhauls fire tube heat exchanger from bending tubes end vertically over against the lower end return cigarette and partly be provided with the ash disposal mouth; The space of the lower end of above-mentioned rotary fire grate also communicates with this ash disposal mouth simultaneously.

The biomass burning hot-water boiler of the present invention that constitutes thus; Its ash disposal mouth can be used for returning the ashes of cigarette part and removing smoothly being accumulated in first backhaul of many backhauls fire tube heat exchanger; Also take simultaneously the burning excess of combustion chamber landing is removed; Make combustion system can keep operation under the efficient unobstructed state, safe and reliable.Get into the water of boiler and the flue gas heat-shift many backhauls fire tube heat exchanger from the water inlet interface, carry out the heat-shift second time with fire tube and time smoke-box once more to the heating water tank space of combustion stove part then; Flow into the peripheral hardware pipe-line system from the water outlet interface at last.Flow through successively above-mentioned time smoke-box, fire tube and many backhauls fire tube heat exchanger heating surface and water of the flue gas that produces behind the biomass fuel combustion carries out being extracted into chimney by air-introduced machine through chimney interface after the exchange heat and gets rid of.Can in time observe the combustion case of stove fuel through feed inlet, stir imperfect combustion coke and burn away.

With prior art relatively, the invention has the beneficial effects as follows: according to this boiler of the combustion characteristics design of biomass molding fuel, the mode of its firing biomass fuel is compared with traditional combustion biomass fuel mode; The present invention changes vertical shell up-downgoing flue in the past and horizontal boiler level front and back row flue, is the flue up and down of vertical shell updraught flue of vertically-arranged and horizontal water tank, and flue dust has realized that a heat exchange absorbs before getting into many backhauls fire tube heat exchanger; Make a large amount of dusts all be deposited on the rotary fire grate like this; Significantly reduce flow resistance, reduced the dust that gets into many backhauls fire tube heat exchanger, improved the heat exchange effect of many backhauls fire tube heat exchanger; Reduced the concentration of emission of flue dust; Help environmental protection, reduced the wearing and tearing of flue dust again simultaneously, improved the service life of equipment fire tube.In addition, the present invention adopts the structure of the heat transfer technology of flue up and down of horizontal water tank, can make water tank do capacity to such an extent that increase the whole height of boiler more greatly and not according to the design requirement of heat production water.Reasonable in design, the compact equipment of the present invention as in the same way, can be alleviated current energy-intensive situation effectively, alleviates greenhouse effects.
