Description
Technical field
The present invention relates to a kind of thermal power transfer equipment that (also claims coal heating, heat carrier) taking heat-carrying working medium as high temperature heat conductive oil, relate in particular to a kind of heat storage type combustion boiler of organic heat carrier.
Background technology
Boiler of organic heat carrier is with coal, heavy oil, light oil, fuel gas and other combustible material are fuel, conduction oil is heat carrier, utilize oil circulating pump to force liquid phase circulation, heat energy is flowed to after hot equipment, then return to the extraordinary industrial furnace of the single flow reheating, be widely used in as petrochemical industry, weaving, printing and dyeing, plastics, rubber, food processing, timber processing, asphalt heating, carton is produced, dewatering vegetable, baking vanish, casting sand mo(u)ld is dried, also can be used for≤350 DEG C bake, evaporate, sizing, dissolve, the industry such as dry, it is a kind of novel desirable heating equipment.
Boiler of organic heat carrier of the prior art, the thermal efficiency is 80%～90% left and right, and the thermal efficiency distributes, and radiant section is about 70% left and right, and convection section is about 30% left and right, and the thermal efficiency is lower.
Summary of the invention
The object of this invention is to provide the heat storage type combustion boiler of organic heat carrier that a kind of thermal efficiency is high.
The object of the invention is to be achieved through the following technical solutions:
Heat storage type combustion boiler of organic heat carrier of the present invention, comprise body of heater, in described body of heater, be only provided with radiant, radiant is provided with the protecgulum and bonnet position or upper cover and the lower cover position that are subject to hot coil and two groups of heat-storage type burners, described two groups of heat-storage type burners to be arranged symmetrically in described body of heater.
As seen from the above technical solution provided by the invention, the heat storage type combustion boiler of organic heat carrier that the embodiment of the present invention provides, owing to only establishing radiant in body of heater, does not have convection cell and flue gas waste heat recovery system, and rate of heat transfer is high; Owing to adopting heat storage type combustion, make the heat content that high-temperature flue gas has pass to the air (or combustion gas) that enters stove burning, air (or combustion gas) can be preheated to only than the high temperature of the low 100 DEG C of left and right of burner hearth, realize High Temperature Air Combustion, the heat of flue gas waste drops to the limit, also make NOx discharge capacity significantly reduce, improved environment protecting; Because heat storage type combustion is a kind of dispersivity burning, whole burner hearth is essentially same temperature, has both improved radiating furnace tube average surface calorific intensity, significantly reduces again the possibility of tube coking.Only establish radiant, there is no convection cell and flue gas waste heat recovery system, rate of heat transfer is high.
