Pressure fire operations and precautions Henan fast boiler's wet back three pass 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 ℃. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!

How pressure hot water boiler the security work in Year 6 at night, is located opposite the old wet back three pass steam boiler certain aquaculture farm town of Rudong Ju Wang Tan explosion cause of the accident is operating a boiler operator improper. Such as shrimp farms in the South East of whitening, the use of the boiler is very extensive, mainly used for farming shrimp shed warming. Before many farms use steam boilers, higher risk, many farms put on a higher level of security pressure hot water boiler. Pressure hot water boiler is no risk, but it does not mean you can neglect of duty fireman. To regularly observe the water level to avoid low water level, the situation appears dry, otherwise there will be a certain risk, but will seriously reduce the life of the boiler using pressure hot water boiler. Boiler operator should note the following: 1, strict implementation of rules and regulations, seriously concerned to learn boiler expertise, and constantly improve the level, to ensure safe and economic operation of the boiler. 2, the pressure hot water boiler in use, organizations and individuals will be allowed to change the structure of the boiler, valves and piping system 3, before the predetermined succession visits to check a variety of devices, comprising: a water tank (hot water tank, expansion tank) , the amount of energy (boiler gas meter), a thermometer (temperature of hot water tank, the boiler water temperature of heat medium) and the like operation, when the shift operation to check the recorded inventory tool, and to learn more about the operation of the boiler. 4, take over staff as required, shift and provisions ahead of time to take over the boiler room to do the preparatory work, and to understand the operation of the boiler. 5, shift work were prepared in advance, be careful and comprehensive inspections and investigations, to keep the boiler running. 6, shift workers should take over personnel issues related to equipment operation, water quality and boiler blowdown, etc., without handing, transfer of personnel shall not leave their jobs. 7, keep the boiler running when the boiler clean, no dirt, no leakage, no rust and corrosion, carefully fill out detailed equipment maintenance records. 8, using the boiler room is one of the vital sectors of the boiler unit, in addition to the boiler room workers, leaders and security, defense, department managers, other unauthorized persons do not access inside. 9, prohibits storage of flammable boiler room and other debris and the like, loaded with a small amount of lubricant required, cleaning the oil drums, oiler, to be stored in designated locations, and pay attention to check whether the explosives combustion. 10, boiler room to be equipped with fire fighting equipment, carefully managed, it should not be moved or used for other purposes. 11, boiler room floors, walls, doors and windows keep clean. 12, competent leadership regularly, irregularly running records, sanitation inspection, identify problems and timely solutions. 13, at the stipulated time to work on time, do well shift recording, not just leave their jobs, leave something. 14, alcohol is strictly prohibited in the boiler room, drowsiness, gambling, fighting once found seriously. After 15, equipment failure and accidents timely reporting (timely reporting on duty the night the person in charge), realistic write a written accident report, to be thoroughly investigated, after clarifying the responsibility, resulting in losses to the accident negligence, be held accountable process.

Primary air tube blockage is what causes? How to prevent? Reason: 1) blocked or coked-burner fire nozzle inlet is blocked portion of small oil gun and other debris. 2) too many impurities coal, powder machine speed is too high, the pulverized coal and primary air speed too low. 3) powder machine speed is too high, too much under the powder without timely blown away. 4) a low pressure (throttle open or not to open too small), can not take away meal. Precautions: 1) to the powder and the rotational speed of the unit load and adjust relevant primary pressure according to the powder not more than 700 rpm rotation speed, a wind speed of each holding 25 ~ 30m / s, the mixed primary air temperature was controlled at 180 to 250 ℃, a pressure depending on the load, depending on coal, in the range 2.5 ~ 3.8kPa. 2) find a wind speed is too low, the primary air temperature is lower than the normal value should be to lower the rotation speed corresponding to the normal to the powder of a primary air temperature and wind speed. 3) open, gas wet back three pass steam boiler tank should be fully cut-off torch powder, the powder in the tube is blown accumulated powder. 4) Fire mouth clogged or coked should try to remove. What causes large vibrations induced draft fan? 1) motor bearings in oil, resulting in large vibration and bearing wear; 2) even when the shaft is mounted on the center not good; 3) induced draft fan stall surge; 4) anchor bolt loosening induced draft fan; 5) blade fouling or wear ,lost balance.
