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. Xinxiang 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 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.

As a pressure vessel, waste heat boiler shall be used reasonably and managed scientifically in the process of use to avoid safety accidents caused by improper use and management. The quality of water is one of the important factors affecting the service life and safe operation of waste heat boiler. The quality of water added into the boiler directly affects the normal operation of waste heat boiler. Xinxiang Gas steam generator The normal delivery of water is the lifeblood of normal boiler use. If the boiler is short of water, it is bound to cause major safety accidents and fatal damage to the boiler. Therefore, it is necessary to ensure continuous and stable water transmission during boiler operation. vertical Gas steam generator manufactor Regardless of the tonnage of the waste heat boiler, the lower configuration of the boiler electric control shall ensure the continuous operation of the boiler water pump, and the water supply pipeline shall be equipped with a water supply regulating valve with good regulation characteristics to control the water supply flow according to the level of the boiler. In addition, in order to ensure that the normal delivery of water will not be affected by the pump failure, a standby pump should be ensured.

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. Xinxiang 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 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.

When the boiler is shut down, the temperature of the heat transfer oil can be reduced to below 70 ℃ before the shutdown of the hot oil pump. In case of sudden power failure, extinguish the fire immediately, and then implement the operating procedures. Otherwise, the furnace tube will be burned out and the loss will be large. According to the type of heat transfer oil boiler, heat transfer oil shall be reasonably selected to prevent overheating. Xinxiang Gas steam generator When purchasing unqualified heat transfer oil, do not save money or mix heat transfer oil indiscriminately. Otherwise, the consequences will be very serious. Prevent the oxidation of heat transfer oil. The strict heat transfer oil is more than 50 degrees in contact with the air, which will make the heat transfer oil crack. Its speed is amazing, and the consequences are relatively serious. After normal operation, the test crew needs to close the exhaust valve on the auxiliary exhaust pipe. After 6 months of use, the heat transfer oil must be sampled and tested according to the instructions. If problems are found, the heat transfer oil must be replaced immediately. vertical Gas steam generator manufactor However, it should be noted that different types of heat transfer oil should not be mixed. The circulation speed of the heat transfer oil should not be less than 1.5m/s. Due to the excessive temperature difference between some entrances and exits, the original design requirements were destroyed, the heat transfer oil could not maintain the original circulation state, the boundary layer became thicker, and the thermal resistance became larger, making the furnace wall exceed the oil film temperature, leading to carbon deposition, cracking, polymerization, coking, and even burning through the furnace tube.

During the operation of the gas generator set, the full combustion of gas and air generates a large amount of heat energy. The heat energy is converted into mechanical energy through the crankshaft connecting rod mechanism, and the generator converts this mechanical energy into electrical energy. However, some of the heat energy is still taken away by the exhaust gas and discharged from the cylinder block, resulting in the exhaust gas emission temperature of 500-600 ℃. In order to avoid this part of heat loss, waste heat boiler is used. If the high-temperature waste gas is directly discharged without treatment, it will inevitably cause excessive temperature in the workshop, accelerate the aging of equipment, affect the service life of equipment, and lead to a large use of cooling circulating water for the unit. If the waste heat boiler is installed, it can not only solve the above problems, but also generate steam energy for production and domestic use in the mine, so as to realize the recycling and comprehensive utilization of resources.
