Abstract
The utility model relates to a coal-gasification-kindling recycling and environment-friendly boiler, which comprises a sandwich style stove wall. A primary air entrance is positioned at the sidewall of a clinker tank. A secondary air entrance is positioned at the sidewall of a radiation heat-exchanging section. A convection heat-exchanging section is provided with a horizontal heat-exchanging tube array which is communicated with the sandwich style stove wall. The convection heat-exchanging section is internally provided with a sandwich style baffle which is communicated with the sandwich style stove wall. A smoke vent at the rear end of the convection heat-exchanging section is sleeved with a round sheath which is internally provided with a coil pipe. Two ends of the coil pipe extend out from the sheath; one end nozzle of the coil pipe is connected with the primary air entrance and the secondary air entrance. The convection heat-exchanging section of the utility model is divided into three procedures of being upward, downward, and then upward by a sandwich style clapboard and the sandwich style baffle in turn; as a result, the utility model is characterized by adequate convection heat-exchanging, low temperature of the exhaust emission, and high heat-transmission efficiency. As the smoke vent is sleeved with the round sheath which is internally provided with a single-layer helix tube that the air blown in is heated first and then transmitted to the radiation heat-exchanging section positioned below a fire grate and in the hearth, thereby the temperature of the hearth is unlikely to greatly decrease. Compared with blowing the cold air directly to the boiler, the utility model can reduce the coal consumption and improve the heat efficiency of the boiler.

Background technology
Coal gasification, and combustion backhaul environment protecting water-heating boiler has the chuck furnace wall, chuck has burner hearth in the furnace wall, continuous radiation heat transfer section and heat convection section are arranged in the burner hearth, between radiation heat transfer section and the heat convection section chuck dividing plate is arranged, the furnace sidewall of radiation heat transfer section has coal filling hole and breast hole, inboard wall of burner hearth in the radiation heat transfer section has refractory insulating layer, there is fire grate the below of radiation heat transfer section, the fire grate below is a cinder chamber, cinder chamber's sidewall has ash disposal mouth and a wind inlet, in the radiation heat transfer section sidewall secondary wind inlet is arranged, the heat convection section has horizontal heat exchanging pipe, and horizontal heat exchanging pipe communicates with the chuck furnace wall respectively, and there is hot water outlet the top of chuck furnace wall, there is cooling water inlet the below of chuck furnace wall, and there is exhaust opening the rear end of heat convection section.In the prior art, the heat convection section has only the flow process of a direction, and flow process is shorter, the horizontal heat exchanging pipe heat exchange in the heat convection section of a direction flow process and the heat convection section of flowing through of elevated temperature heat flue gas, heat convection is insufficient, and exhaust gas temperature is higher, and the thermal efficiency is lower; In addition, wind inlet and secondary wind inlet directly communicate with outside air, and wind and secondary wind that boiler blasts to boiler when burning are the cold wind in the boiler external world, and a large amount of cold wind blast burner hearth, can reduce fire box temperature greatly, have increased coal consumption.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of heat convection fully, wind blasting and the secondary wind coal gasification, and combustion backhaul environment protecting water-heating boiler that can not reduce fire box temperature.
The utility model is realized with the following method.
Coal gasification, and combustion backhaul environment protecting water-heating boiler has the chuck furnace wall, chuck has burner hearth in the furnace wall, continuous radiation heat transfer section and heat convection section are arranged in the burner hearth, between radiation heat transfer section and the heat convection section chuck dividing plate is arranged, the furnace sidewall of radiation heat transfer section has coal filling hole and breast hole, inboard wall of burner hearth in the radiation heat transfer section has refractory insulating layer, there is fire grate the below of radiation heat transfer section, the fire grate below is a cinder chamber, cinder chamber's sidewall has ash disposal mouth and a wind inlet, in the radiation heat transfer section sidewall secondary wind inlet is arranged, the heat convection section has horizontal heat exchanging pipe, horizontal heat exchanging pipe communicates with the chuck furnace wall respectively, there is hot water outlet the top of chuck furnace wall, there is cooling water inlet the below of chuck furnace wall, there is exhaust opening the rear end of heat convection section, the chuck deflection plate is arranged in the heat convection section, chuck dividing plate and chuck deflection plate communicate with the chuck furnace wall respectively, be with cylindrical outer cover on the exhaust opening, the individual layer helix tube of useful steel pipe coiled in the cylindrical outer cover, the axis of individual layer helix tube and the axis of exhaust opening are on same straight line, and the individual layer helix tube two ends mouth of pipe stretches out from cylindrical outer cover respectively, and an end mouth of pipe that stretches out links to each other with the secondary wind inlet with a wind inlet.
Before the use, in the boiler chuck, be full of water, at the other end mouth of pipe connection air blast of individual layer helix tube.During boiler work, air blast the individual layer helix tube of air in cylindrical outer cover from a wind inlet and the secondary wind inlet is sent under the fire grate and the radiation heat transfer section of burner hearth in, burn on the fire grate of coal in burner hearth, the imflammable gas that coal burning produces burns in the radiation heat transfer section, after coal fully burns, finish heat exchange in the radiation heat transfer section, enter the heat convection section, the heat convection section is because have chuck dividing plate and chuck deflection plate, the heat convection section is divided into upwards successively, downwards, three flow processs make progress, the elevated temperature heat flue gas flows through in the heat convection section upwards successively, downwards, upwards three flow processs are carried out convective heat exchange, heat convection is abundant, exhaust gas temperature is lower, and the thermal efficiency is higher; Hot flue gas after the cooling is discharged through exhaust opening, hot flue gas exhaust opening after the cooling can heat the interior individual layer helix tube of cylindrical outer cover of exhaust opening when discharging, the air heat that air blast is blasted through the individual layer helix tube, air after the heating from a wind inlet and the secondary wind inlet is sent under the fire grate and the radiation heat transfer section of burner hearth in, can not reduce fire box temperature greatly, compare with directly blasting cold air, can reduce coal consumption, improve boiler thermal output.
Below in conjunction with accompanying drawing, the utility model is further described.
