Description

The biomass-burning normal-pressure hot-water boiler

Technical field

The utility model belongs to boiler, particularly a kind of biomass-burning normal-pressure hot-water boiler.

Background technology

At present, domestic civilian heating boiler generally is a coal-burning boiler, and present shortage along with coal resource; The price of coal rises steadily, and makes the cost of coal-burning boiler heating increasingly high, and coal fired boiler discharging cigarette does not meet environmental requirement yet; The straw gasification stove that arises at the historic moment is in civilian heating, cook etc. to be used widely, but its only is fit to one at family; Can not supply many families or large-area room to use, and the time that straw gasifying needs is long.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of fuel convenient, and calorific value is high, and smokeless emission meets the biomass-burning normal-pressure hot-water boiler of environmental protection.

The technical scheme that the utility model technical solution problem adopts is: the biomass-burning normal-pressure hot-water boiler comprises frame pillar, framework platform, boiler jacket body, flue, heat pipe, fire door, is characterized on the frame pillar, establishing framework platform fixing fuel tank below the framework platform right side; Corresponding fuel tank is provided with fuel and ejects mouth on framework platform, and plate shape piston is housed in the fuel tank, and piston rod connects hydraulic lifting mechanism below the plate shape piston; Lifting decelerator is equipped with in the lower right in hydraulic lifting mechanism, is provided with carriage below the hydraulic lifting mechanism, the track that frame pillar inboard fixing two is parallel; Slide mechanism below the hydraulic lifting mechanism slides on the rail under track, fixedly establishes four trundles below the framework platform, and trundle is connected with rolling above the track; On the frame pillar, adorn the boiler jacket body with boiler jacket body holder; Establish flue in the boiler jacket body, in flue below, the framework platform face above adorn the furnace wall of an inversed taper platform shape, on the furnace wall, establish several air vents; Establish an air compartment in the boiler jacket body below flue, outside the furnace wall; The outside of air compartment connects air blast, and the inside of air compartment connects burner hearth through the air vent on the furnace wall, on flue, establishes several heat pipe; The below wall of boiler jacket body is provided with fire door, and fire door is provided with visor.

The beneficial effect of the utility model is: the biomass-burning normal-pressure hot-water boiler is biomass burning directly, and like fuel such as cow dung, stalk particles, fuel is extensive; Last fuel is convenient, sufficient combustion, smokeless emission; Boiler hot-water is heated soon, and a boiler can satisfy the heating needs of 400 ~ 500 square meters.Feed mechanism can also be used manual material loading, saves equipment cost, and burning cow dung is the fuel saving expense, solves the big problem of cow dung contaminated environment again.
