Description
Technology neck a fabulous creature, said to be like a turtle and blow poisonous sand in man's face
The utility model relates to a kind of combustion equipment technical field, specifically is to utilize fuel combustions such as coal, stalk to produce the gasification burning device of inflammable gas.
Technical background
Existing gasification burning apparatus structure is single, and the burning area of fuel is excessive, combustion gas speed instability, select in the starting material utilization little, or only at coal, or only at stalk, easily coking in the burner hearth, the combustion gas utilization ratio of generation is not high, does not reach the purpose of energy-saving and environmental protection.
Summary of the invention
Prior art is not enough to provide a kind of can utilize that raw materials such as coal, stalk can be stable smoothly produce inflammable gas and draw and efficiently utilize, the multifunctional gasification stove of while energy-conserving and environment-protective to the utility model in order to overcome.
The purpose of this utility model is achieved through the following technical solutions: a kind of coal-fired stalk nozzle-type multifunctional gasification stove, include body of heater, heating water tank, burner hearth, burner hearth blast pipe and smoke exhaust pipe, furnace body inside is provided with interlayer and forms heating water tank, the bottom is provided with fire grate in the body of heater, deslagging chamber is formed at the fire grate bottom, burner hearth is formed at fire grate top, be provided with flame retardant coating around the burner hearth, lower furnace portion is provided with hotair chamber, hotair chamber communicates with heating water tank by pipeline, on pipeline, be provided with the atomizing water valve, the burner hearth blast pipe is provided with the burner hearth air door, upper furnace is provided with a gas outlet chamber, wherein also include a combustion unit, described combustion unit is by the outer tubbiness housing that has perforate, the interior tubbiness housing that is inverted in outer tubbiness enclosure interior constitutes, the perforate of outer tubbiness housing covers in gas outlet, be provided with the combustion gas adjustment doors at tapping, outer tubbiness housing has the secondary air mouth, this secondary air mouth and interior tubbiness enclosure interior, communicate between outer tubbiness housing and the interior tubbiness housing, the sidepiece of interior tubbiness housing and top all evenly have the gas jet hole.
Materials such as fire coal, stalk add burner hearth and smoulder, and spray water by hotair chamber, through pyrolytic gasification water generation reaction coal gas (carbon monoxide) inflammable gas after gas outlet is delivered to gas combustion apparatus, the gasification reaction required air is entered by the burner hearth blast pipe in the burner hearth, help the pyrolytic gasification reaction, the combustion gas that produces in the burner hearth is fully burnt through a plurality of nozzles at gas combustion apparatus, improves thermo-efficiency.The utility model is simple in structure, and is easy for operation, and save energy reduces environment and topsoil.
The utility model is compared with similar vapourizing furnace has salient feature: 1, the operation adult is low, is applicable to fire coals such as bituminous coal, brown coal, and combustiblematerialss such as timber, stalk; 2, thermo-efficiency height, quick heating, by repeatedly training wind, nozzle-type burns, no tar, nozzle does not stop up, and smokeless, dust concentration is low, and burner hearth is not tied reef, and is not high to the requirement for height of chimney; 3, gas production rate is big, and quality is good, and firepower is prosperous, and it is big and stable to regulate load range, and burner hearth is reinforced long at interval, generally can 6～8 hours, and fire-sealing time is long, can reach more than 24 hours.The utility model use range is wide, can be used for all respects such as heat supply stove, steam oven, hotblast stove, plastic working.
