Be equipped with relief tube on described high-temperature water tank and the reservoir, this relief tube communicates with hot water storage tank.
Combined hot homogeneous solution-type reactor of the present utility model has following technical characterstic:
1. this boiler body is to be combined by the accumulation of heat drum that has the pressure release function concurrently, the warm water drum that has dedusting function concurrently and high temperature drum three parts, and this design can realize the split transportation, install, and its maintenance, simple to operate is installed reliable;
2. the utility model aids in high temperature air feed, multistage combustion-supporting when adopting naked light just burning, and has realized the diffusing burning of bituminous coal smokeless, energy-conserving and environment-protective;
3. the utility model adopts water (flow) direction counter-flow arrangement in high-temperature flue gas and the body of heater, and temperature and pressure are big, make full use of waste heat, can realize the secondary utilization of flue gas;
4. the utility model is provided with diclinic arch in the burner hearth of high temperature drum, makes coal-firedly when the burner hearth internal combustion, and flame is not directly to wash away the heat exchanging water pipe but carry out second-time burning after being introduced into the diclinic arch, to reach sufficient combustion, clean purpose;
5. directly do not discharge after the flue gas that the utility model produced finishes heat exchange in the high temperature drum, and enter the backward erosion of warm water drum by flue, discharge from throat after entering the retaining drum at last, make whole flue gas trend be " N " shape, thereby prolonged flue gas flow, realized smoke elimination depositing dust, energy-saving effect;
5. the water endless form adopts height to advance to exceed in the body of the utility model boiler, it is the exhaust opening that water feed apparatus is installed in boiler, high-temperature flue gas that utilization will be discharged and steam, cold water is once heated at this, enter the warm water drum by convection tube subsequently, utilize the interior smoke convection heat of body of heater to carry out post bake; Enter the high temperature drum at last, utilize flame radiation heat to carry out three heating, whole process is the W counter-flow arrangement, the W type water supplementing method of this uniqueness, partial heat energy (flue gas heat energy and steam thermal energy) the secondary recovery utilization that body of heater originally will be able to be destroyed in running is with the effect that reaches the further raising thermal efficiency and economize on coal, through measuring and calculating, combination style at normal pressure boiler of the present utility model improves 76.9% than traditional normal-pressure boiler thermal efficiency, economizes coal 35%-50%.
Combination style at normal pressure boiler of the present utility model has really been realized when economizing on coal, and improves the thermal efficiency, has solved the problem of energy savings; In bituminous coal, realized the diffusing smokeless that burns of bituminous coal, solved problem of environmental pollution.
