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. Tianjin Fuel gas 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 gas 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.

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. Tianjin Fuel gas 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 gas 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.

Effectively prevent and reduce low temperature corrosion of air preheater. Low temperature corrosion is caused by sulfur dioxide generated by combustion of sulfur in fuel. Tianjin Fuel gas steam generator Under the action of catalyst, sulfur dioxide is further oxidized to sulfur trioxide. Sulfur trioxide and water vapor in the flue gas generate sulfuric acid vapor, which greatly increases the dew point of the flue gas, condenses the sulfuric acid vapor on the flue gas side of the preheater tube wall, causing sulfuric acid corrosion of the preheater. The content of sulfur trioxide has a great impact on the corrosion rate of the preheater. The content of sulfur trioxide is not only related to the sulfur content in the fuel, but also related to the oxygen content in the flue gas. vertical Fuel gas steam generator manufactor Low oxygen combustion can significantly reduce the oxygen content in flue gas, greatly reduce the amount of sulfur dioxide oxidized to sulfur trioxide, reduce the dew point of flue gas, and effectively reduce the corrosion of preheater. Low oxygen combustion reduces the amount of flue gas. It can not only reduce the exhaust gas temperature, improve the boiler efficiency, but also reduce the power consumption of the forced draft fan and the wear of the heating surface.

The steam generator pressure controller is used to control the generator, because it has no water level display, no board control, and its heating control is mainly controlled by the floating water level controller. Tianjin Fuel gas steam generator When the water level is moderate, the floating point is connected to the control voltage to operate and heat the AC contactor. The generator has a simple structure and is currently used in the market. The common non heating fault of this generator is mainly found in the float level controller. First check the external wiring of the float level controller, connect the upper and lower control lines, and then remove the float level controller to see if it is flexible. vertical Fuel gas steam generator manufactor You can use the manual to use the meter to determine whether the upper control point and the lower control point can be connected. Check the equipment and check for water. The float can fill the fuel tank, replace the float, and eliminate faults.

Biomass boilers can be roughly divided into two categories according to their uses: one is biomass thermal energy boiler, and the other is biomass electric energy boiler. Tianjin Fuel gas steam generator In fact, the principle of the two is basically the same. Both obtain energy by burning biomass fuel, which is just one way to directly obtain heat energy. The second way is to convert heat energy into electric energy. Among the two boilers, one is widely used and has mature technology. If we continue to subdivide, one kind of boiler - biomass heat energy boiler mainly has the following two types: one is small biomass heat energy boiler. vertical Fuel gas steam generator manufactor The boiler uses solidified or gasified biomass fuel to provide heat energy in the form of hot water. Its advantages are small size, simple structure and low price; Class II: medium-sized biomass heat energy boiler. Such boilers mainly use solidified biomass fuel to provide hot water or steam. Its advantages are relatively mature technology, small energy loss and strong heat supply capacity.

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 Fuel gas steam generator 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. vertical Fuel gas steam generator manufactor 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.
