Pressure fire operations and precautions Henan fast boiler's conductive oil most popular steam boiler Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃.

Solutions and prevention of gas oil-fired boiler flameout Today we'll resolve what about gas fuel boiler flameout solutions and prevention fuel gas-fired boiler flameout Solution: First, the furnace pressure gauge indicates the value suddenly increases, the furnace black can not see the flame, burning furnace sounds disappear, extinguishing the flame supervision devices emit a signal; the temperature dropped sharply atmospheric pressure, the water level dropped after the first rise, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply as a result of intermittent, the boiler is oil or gas pressure drops to zero, only a single burner flame, the furnace may also be thrown skew central flame extinguished burner pressure change; as a result of the fuel supply interruption, the extinguished burner pressure or hydraulic indication may drop to zero, and the fuel consumption, the gas pressure is increased other operating burner. Causes gas boiler flameout are: sudden increase in gas pressure caused from the fire, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause the boiler flame. Cause misfire has oil-fired boiler: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water. After the explosion should be taken to prevent the furnace boiler flameout, it must immediately cut off the fuel supply to the furnace, and then block the electromagnetic valve of the gas supply valve to seal off the fuel supply to run the burner. When the action to be fast in order to avoid inheritance or restore fuel supply during operation, causing the furnace explosion. And identify the cause of boiler flameout troubleshooting find a good job and then start the preparatory work. Before starting the boiler should be enhanced ventilation purge, purge time is more than 5min, then procedures ignition. It is forbidden to send fuel directly to the high-temperature furnace without using an ignition spark ignition device to prevent furnace explosions. If due to fan failure caused when the flame should be quickly cordoned off the fuel supply line of each valve, with special attention because the valve is not tight blockade caused by leaking fuel. Ventilation and purging of the furnace and flue in accordance with the approach of an emergency shutdown. Ignition step by step in the recovery operation after the fan. Single burner flame burner only block the fuel supply valve, the burner off a small damper identifying and troubleshooting and then re-ignition by the ignition process. Boiler flameout of prevention: For oil-fired boiler should minimize the possibility of fuel transport, storage and handling of water in all sectors. Tank initiative measures should dehydration and dehydration on schedule. In any case, it should ensure the security of oil supply. The supply of oil and acceptance testing, cutting oil change when the master species. When a large change in oil types, varieties and the need for the oil tank to store the original varieties contaminated test to determine whether the same storage tank, to prevent the density and viscosity differences between a large number of decomposed oil mixed insoluble material, clogging oil pipeline. For the operation of the gas boiler should be closely monitoring the evolution of gas pressure, the timely processing of exceptions thrown up air pressure, ensure the supply pressure in the normal range. To always understand, repair gas composition, gas composition changes when large, to take the necessary adjustment measures on the boiler operation.
