The invention discloses a furnace with a waste heat utilization system. The furnace is that: the rear part of the furnace main body is connected with the waste heat utilization system, wherein the waste heat utilization system comprises a waste heat boiler device; the waste heat boiler performs heat exchange with furnace smoke gas through an evaporator which is formed by a spiral fin arranged at the bottom of the waste heat boiler, so that a certain amount of vapor which is generated by heating water in the boiler is used by a user; and the smoke gas after reducing temperature by heat exchange is drew out by a draft fan and discharged through a chimney. The furnace with the waste heat utilization system of the invention can fully utilize the heat source of high temperature furnace smoke gas to generate the vapor to be used by the user, reduce the waste of energy source and satisfy the new industrial structure of energy-saving and emission reduction popularized by the country.
Description
technical field [0001] The invention relates to the technical field of calcining kilns, in particular to an industrial kiln with a waste heat utilization system. Background technique [0002] A kiln is a device made of refractory materials to calcine materials or products. Various kilns for burning paper pottery appeared in China very early. required devices. According to the variety of calcined materials, kilns can be divided into brick kilns, porcelain kilns, pottery kilns, cement kilns and other kilns. Because the firing temperature inside the kiln is very high, the high-temperature waste heat flue gas after firing in a traditional kiln is directly discharged out of the chimney, which will cause a lot of waste of heat sources. Contents of the invention [0003] Aiming at the waste of heat source caused by the direct discharge of high-temperature waste heat flue gas in traditional kilns, the present invention proposes a kiln with a waste heat utilization system, which ...
