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 Horizontal fuel gas 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 Horizontal fuel gas 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.

As a large equipment, the maintenance of gas-fired hot blast stove is one of the things that must be done. Heilongjiang Horizontal fuel gas 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 Horizontal fuel gas 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.

After the cold furnace of oil fired and gas fired boiler is ignited, the speed of temperature rise shall be controlled at 10 ℃/hour, mainly because the viscosity of oil temperature is large when it is cold, and the flow rate in the heating surface pipe of the whole equipment is relatively low. Heilongjiang Horizontal fuel gas steam generator The oil film on the pipe wall is thick, so the heat transfer condition is poor when in use. If the heating speed of oil and gas fired boiler is too fast during use, it is easy to make the local oil film temperature too high. The equipment is in the stage of driving away the residual moisture and moisture contained in the heat conduction fluid in the system within the temperature range. vertical Horizontal fuel gas steam generator manufactor In oil and gas fired boiler, when the steam exhaust volume at the vent pipe of the expander is relatively large, there will be water hammer at the bottom of the equipment. In this way, the vibration of the pipeline will accelerate, and when the swing amplitude of the pressure gauge pointer in each part of the equipment is large, the temperature rise will be stopped and the constant temperature state will be maintained.

Waste heat boiler is a kind of industrial equipment. Although the equipment is simple to operate, it also needs special attention in practical application. Heilongjiang Horizontal fuel gas steam generator So what should we pay attention to when it runs? Generally, when using waste heat boiler, we need to pay attention to prevent misfire. Due to the excessive output of the burner, the flame will disengage from the burner, resulting in incomplete combustion. A large amount of mixed gas in the furnace may cause explosion, and backfire should also be prevented. Due to the low output, the flame will retract into the burner, resulting in unstable flame flameout vertical Horizontal fuel gas steam generator manufactor If the combustible gas continues to enter the limit, it may cause explosion. After ignition, pay attention to adjust the combustion gas flow, stabilize the burner pressure, so that the flame can burn stably. In order to reduce the smoke from the chimney and pollute the environment, smoke suppression and dust removal devices should be installed.
