As is known to all, the boiler using sensible heat of various waste gases and waste heat after waste incineration as heat source is called waste heat boiler, also called waste heat boiler. Therefore, the country advocates vigorously developing waste heat utilization, energy conservation and emission reduction, which plays a positive role in protecting energy and improving the quality of human living environment. Heilongjiang Fuel oil steam generator In the design of waste heat boiler, how to reasonably divide the temperature range is the basis for reasonably arranging the heating surface of waste heat boiler and making maximum use of waste heat. Under the condition of a given exhaust gas temperature at the inlet of the waste heat boiler, there are two requirements for the exhaust gas temperature. One is to limit the exhaust gas temperature, which is required to be within a reasonable range; The other is that the exhaust gas temperature is not limited, requiring greater use of waste heat. vertical Fuel oil steam generator manufactor In either case, for medium and low temperature waste heat utilization, the narrow point temperature difference directly affects the evaporation capacity of the waste heat boiler and the layout of the heating surface. Narrow point temperature difference, also known as node temperature difference, is a small temperature difference between evaporator outlet flue gas and heated saturated water vapor during heat exchange. With the change of narrow point temperature difference, the relative total heat exchange area, relative evaporation capacity and relative exhaust gas temperature of the waste heat boiler also change.

Enterprises that rely on coal for power generation are both traditional power enterprises and highly polluting enterprises. The industrial waste gas discharged by coal power generation enterprises has seriously polluted our living environment. Heilongjiang Fuel oil steam generator As a result, the country has become more and more strict in the control of this industry, and how to use waste heat recycling power generation has become a topic of concern for many enterprises. Waste heat boiler can meet this demand of enterprises, so its application in coal mine power generation enterprises is more and more. vertical Fuel oil steam generator manufactor Installing a waste heat recovery boiler on the exhaust pipe of the coal mine gas generator set, using the waste heat discharged by the coal mine gas generator set to generate steam for power generation, can not only turn waste into treasure to realize the secondary utilization of energy, achieve the goal of combining coal mine gas control with energy conservation and emission reduction, but also reduce environmental pollution, kill two birds with one stone.

As a large equipment, the maintenance of gas-fired hot blast stove is one of the things that must be done. Heilongjiang Fuel oil steam generator Regular maintenance can not only keep the hot blast stove clean, but also improve the service life of the hot blast stove. Therefore, it is the top priority in the use of hot blast stove. Today's editor will tell you how to maintain the hot blast stove regularly. In many manufacturers that use hot blast stoves, in order to better develop the enterprise, it is necessary to increase the number of hot blast stoves and improve the performance of hot blast stoves. vertical Fuel oil steam generator manufactor When enterprises purchase hot blast stove equipment, they must understand their own needs and the products of hot blast stove manufacturers in the market. Therefore, the small edition of gas-fired hot blast stove tells us the problems to be considered in the selection of hot blast stove.

System oil drainage: drain the heat transfer oil in the system when the circulating heat transfer oil is between 120 ± 5 (if the oil is not replaced, please find a clean container for proper storage) 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. Heilongjiang Fuel oil steam generator 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. vertical Fuel oil steam generator manufactor 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 hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Heilongjiang Fuel oil steam generator When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged from the tank, the resin will resume the softening exchange function. vertical Fuel oil steam generator manufactor Since the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange and softening treatment, the principle is to pass raw water through sodium type cation exchange resin, so that the hardness components Ca2+and Mg2+in the water can exchange with the Na+in the resin, thereby adsorbing Ca2+ Mg2+， Soften the water.
