The waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Shenyang Gas steam generator In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. vertical Gas steam generator how much Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

The air storage tank in the air source system shall be installed behind the rear cooler, so as to prevent oil vapor and liquid water from gathering in the tank and reduce potential safety hazards as far as possible; The lower temperature of other air stored in the tank can also reduce the volume of the body. Shenyang Gas steam generator When connected with screw compressor and other air supply equipment, the air receiver can be installed behind the dryer. At this moment, the air entering the air receiver is dry and there is no condensate in the tank. The air tank is a pressure vessel, and each air tank shall be equipped with safety valve, pressure gauge and other necessary safety supervision equipment. vertical Gas steam generator how much The application and maintenance shall strictly comply with the relevant provisions of pressure vessels; The air tank shall be equipped with a manhole or hand hole for maintenance, and the lower part of the tank shall be equipped with a drain valve, which shall be regularly drained; The air storage tank is usually installed outdoors, so it should be protected from direct sunlight and there should be no high temperature heat source nearby.

The produced waste heat boiler for hazardous waste incineration is a natural circulation water tube boiler, which adopts a single drum vertical layout and a full membrane water wall structure. Shenyang Gas steam generator The surrounding, top and three middle membrane water-cooled walls form a tight series of heat exchange flues. The convection heating surface is no longer arranged inside the heat exchange flue, and radiation heat exchange is adopted, so as to ensure the smooth flow of high-temperature flue gas containing strong coking adhesive ash in the heat exchange flue. Full automatic shock soot blower is arranged on the membrane water wall, and inspection holes and observation holes are reserved. vertical Gas steam generator how much The bottom of the boiler is composed of membrane water walls on both sides to form a water-cooled ash bucket, and the lower part is connected with a closed spiral ash extractor. The settled soot in the waste heat boiler and the ash removed by the soot blower are discharged out of the boiler by the ash extractor. The furnace wall is of pipe laying structure, and the outside is covered with corrugated steel plate.

The waste heat boiler for hazardous waste incineration is an important part of the hazardous waste rotary kiln incineration system. The heat source is the high-temperature waste gas containing strongly coking and cohesive ash after hazardous waste incineration. Shenyang Gas steam generator Generally, this type of waste heat boiler adopts single flue or multi flue layout, and convection heating surface is arranged in the flue. During operation, strongly coking cohesive ash is easy to adhere to the convection heating surface, leading to flue blockage, affecting the safe and normal operation of the waste heat boiler. According to the characteristics of hazardous waste rotary kiln incineration system, a kind of waste heat boiler with special structure suitable for the system was developed, which successfully solved the problems of ash deposition, wear, air leakage, corrosion, etc. vertical Gas steam generator how much The water circulation mode of the waste heat boiler is natural circulation. The working medium directly enters the drum, then is led out from the drum, flows into each membrane water wall through the downcomer, is heated here, then led back to the drum through the steam conduit, and is separated by the steam water separator, and then led out of the drum saturated steam with rated parameters.
