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. Tianjin Waste heat boiler 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. small-scale Waste heat boiler 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.

Waste heat boilers are widely used in high energy consumption industries. There are two common types of waste heat boilers: one is used to recover the exhaust gas emitted by ordinary boilers, such as fuel fired and gas-fired boilers, biomass fired boilers, etc. The temperature of the exhaust gas from ordinary boilers is about 600 ℃, which is not too high, Therefore, the requirements for waste heat recovery boiler are relatively low. Tianjin Waste heat boiler The other is industrial waste heat recovery boiler, such as building materials industry, chemical industry, steel making industry, etc. The temperature of waste gas and waste heat in these industries is high, and the recovery and utilization are also quite valuable. small-scale Waste heat boiler how much Henan Yuji Boiler Vessel Manufacturing Co., Ltd., founded in 2005, is located at No. 8, Jizhong Road, Xiaoji Town, Xinxiang County, Henan Province. It is a comprehensive enterprise of boiler and pressure vessel, mainly engaged in the manufacturing of boilers and pressure vessels, with technological innovation as the core, integrating the design, manufacturing, sales, installation, transformation and maintenance of boilers and pressure vessels.

In the chemical industry, the electric heating heat conduction oil furnace is used for distillation, evaporation, polymerization, condensation, steel gate, fatliquoring, monotony, melting, dehydrogenation, forced heat preservation, and the heating of equipment composed of pesticides, intermediates, antioxidants, surfactants, spices, etc. Tianjin Waste heat boiler In the plastic and rubber industries, the electric heating heat conduction oil furnace should be used for heating and insulation of hot pressing, hot rolling, kneading, kneading, internal mixing, vulcanization molding, jet injection molding machine, slurry mixer, conveyor belt dryer, screw kneading machine and mold. In metallurgy, machining and casting industries, electric heating heat conduction oil furnaces are used to heat metal degreasing tanks, dewar tanks, electric gate valves, cleaning tanks, electroplating tanks, aluminum plate oxidation tanks, electrode manufacturing, shower heat treatment equipment, phosphate treatment equipment, baking machine rooms, sand core drying, varnish spraying and monotonous equipment. small-scale Waste heat boiler how much In the food industry, the electric heating heat conduction oil furnace should be used for bread baking equipment, biscuit food baking equipment, candy production equipment, grain monotone equipment, cooking oil pressing and refining equipment, distillation pot, autoclave, conveyor belt dryer electric heater equipment.

System oil drainage: circulate the heat transfer oil between 120 ± 5 to drain the heat transfer oil in the system (if you do not replace the oil, please find a clean container to store it properly). Prepare an appropriate amount of coke removal cleaning agent for the heat transfer oil system, drain the oil in the gas-fired heat transfer oil boiler system, and disconnect the cleaning system from the oil storage tank (close the valve), including the connection between the high-level tank and the oil storage tank. Tianjin Waste heat boiler Residual oil blowing steps: connect the air compressor at the pressure gauge or other places that can be connected, boost the system to 0.3-0.4MPa, and discharge it instantaneously; Repeat this process until the residual oil is blown out. The gas-fired heat transfer oil boiler, circulating pump, and other heat users form a cleaning circulating circuit for decoking and cleaning: add diluted cleaning agent to the system and fill it up to 1/2 of the water level of the high-level tank. Dosage of coke removal cleaning agent: 10~20%, the specific dosage shall be determined according to the scale thickness. Temperature: 90-95, time: 12-72 hours, which can be determined according to the scale thickness. Rinsing and cleaning: after cleaning, drain the residual liquid in the system and add clean water to rinse twice until the coke remover is free of foam and the water is clear. small-scale Waste heat boiler how much Temperature: 85-95, time: 5-8 hours Water blowing steps: after cleaning, connect the air compressor at the pressure gauge or other places that can be connected, use compressed air to boost the system to 0.3-0.4 MPa, and vent at each low point. Repeat this process until the water is blown out. Waste liquid treatment: the cleaning waste liquid generated in the cleaning process is discharged after being treated in the biochemical tank.

The fluctuation of waste heat boiler flue gas in flow, temperature, composition, dust content and other aspects is one of its characteristics. The nature of the fluctuation can be regular, periodic, or irregular, aperiodic; The characteristics of fluctuation can be gradual. Tianjin Waste heat boiler It can also be impulsive; It can be a single parameter or a composite fluctuation of multiple parameters. The selection of waste heat boiler shall first analyze the whole cycle of the main process flow, and determine the flue gas characteristics of each time section in the cycle. small-scale Waste heat boiler how much Therefore, corresponding measures shall be implemented one by one in the design of waste heat boiler. The prominent feature is often the main basis for the selection of waste heat boiler.

To understand the advantages and disadvantages of hot blast stove and hot water stove, we should start from the working principles of the two boilers. The hot water boiler can increase the indoor temperature by burning hot water, circulating hot water, heat dissipation, etc. General purpose (radiators, floor heating pipes, water heating air conditioners are generally used for heating in families, enterprises and institutions). Tianjin Waste heat boiler The hot blast stove can increase the indoor temperature by heating the air. Generally, a hot channel wind belt is required. It is generally used for workshop, breeding, planting and special heating or drying. Most areas in northern China are cold, such as the three northeastern provinces, Inner Mongolia, Xinjiang and other cities. The colder temperature is more than minus 40 degrees Celsius. There are hot water boilers and steam boilers for heating. Its disadvantage is that it is afraid of circulatory system failure or power failure. small-scale Waste heat boiler how much Once the power failure exceeds two to three hours, if the insulation is not good, the pipeline will freeze. The heating of hot blast furnace is not frozen, and the temperature can be set. It can save 40% energy than hot water heating and 50% energy than steam boiler heating. This comparison is practical. The hot blast stove does not need to apply for a use certificate, the steam boiler and pressure hot water boiler need to apply for a use certificate, and the functional department also needs to carry out annual inspection every year, but also has to bear the cost.
