Shandong Meilin Sanitary Ware Co., Ltd. has seven ceramic firing tunnel kilns and shuttle kilns, which emit a large amount of high-temperature flue gas every day. This project is to use this part of the waste heat to recover the hot water to store it for drying in the molding workshop at night. Since its use in 2017, it has successfully recovered waste heat.

Application of waste heat recovery device in the iron and steel industry Shanghai No. 8 Iron and Steel Plant uses a gas-gas waste heat recovery device on the rolling furnace of the fourth workshop to preheat the combustion air from 20 ℃ to 80-90 ℃, and reduce the exhaust gas from 280 ℃ to At 190 ℃, the waste heat recovered per hour is 419 MJ. In addition, a gas-liquid waste heat recovery device was installed on the rolling mill heating furnace in its third workshop as a waste heat boiler. The exhaust gas from the rolling mill furnace was reduced from 350 ° C to below 300 ° C, and the heat recovery per hour was 47.7 MJ. The standard coal is 11.59 t, and the economic benefits are remarkable. The second-phase project of Maanshan Iron and Steel and Baosteel adopts a heat pipe waste heat boiler to recover 300 ~ 400 ℃ exhaust heat of the ring cooler, and generates steam for preheating the sintered mixture or domestic heating.


The 7 # blast furnace of Maanshan Iron and Steel Works put into operation a heat pipe air preheater, which reduced the exhaust gas from 290 to 370 ℃ to 150 ℃, the preheating air temperature from normal temperature to 200 ℃, and the device recovered 3.39 GJ per hour. Save 40% on burning gas. Application of waste heat recovery device in nitrogen fertilizer industry The waste heat recovery of the gas production section of the fertilizer plant is the main link for reducing ammonia consumption. The process waste heat of the gas production section includes: upward gas sensible heat, downward gas sensible heat, blown gas sensible heat, and combustion. Heat, which accounts for more than 40% of the waste heat of the ammonia synthesis process. This part of the waste heat has a higher heat level and a greater use value.


Small and medium-sized nitrogen fertilizer plants use waste heat recovery devices to recover waste heat from semi-water gas and blower gas. The semi-water gas releases heat through a heat pipe evaporator, and then sends it to the scrubbing tower after cooling down. The blown air is cooled down and vented. The steam pipe is sent to the deaerator or entered into the steam pipe network for further use.

The exhaust temperature of the first-stage conversion furnace of a large-scale fertilizer plant is generally between 250 and 300 ° C. The waste heat of this part of the flue gas is recovered by a waste heat recovery device, which is used to heat the combustion-supporting air. The recovered heat per hour equals about 1.027 t of fuel light diesel.
