Common Problem and Solution gas boiler 1, the power supply is turned on, by cause of failure is not running after starting the motor are: (1) locking pressure less; (2) solenoid valves lax, joints leak, check the lock; (3) thermal relay opens; (4) condition loop at least one is not satisfied (water level, pressure, temperature, and the programmable controller is powered starter) Remedy: (1) adjusting the air pressure to a predetermined value; (2) cleaning or repair of the solenoid valve conduit linker; (3) press the reset element checks whether the motor current and damage; (4) check the water level, pressure, temperature gauge 2 if, after the normal purging before the start, but misfire malfunction Cause: (1) the amount of electric anger ; (2) the solenoid valve does not work (the main valve, an ignition valve); (3) a solenoid valve burned; (4) pressure instability; (5) the air volume is too large Remedy: (1) inspection and repair line; (2 ) renewal; (3) to adjust the pressure to a predetermined value; (4) decreases with the wind, to reduce the throttle opening 3, misfire, normal air pressure, there is no ignition power failure causes: (1) the ignition transformer burnout ; (2) high-voltage damage or loss; (3) the gap is too large or too small, the relative size of the firing rod position; (4) and electrode breakage or Short circuit; (5) inappropriate pitch, Remedy: (1) renewal; (2) or re-install new ones; (3) 4 readjust after the 5S flame lit, fault cause: (1) is less than atmospheric pressure, too much pressure drop, gas flow is small; (2) air flow rate is too small, incomplete combustion, darker smoke color; (3) the air volume is too large, the gas appears white Remedy: (1) re-adjusting the air, the filter cleaning ; (2) 5 readjusted, fault cause white smoke: (1) air flow rate is too small; (2) too much humidity; (3) a lower exhaust gas temperature, Remedy: (1) transfer of small damper; (2 ) appropriate to reduce the air volume and improve the inlet air temperature; (3) take measures to increase the exhaust gas temperature 6, chimney dripping failure reasons: (1) ambient temperature is low; more (2) a small fire combustion process; (3) gas hydrogen-peroxide amount generated water; (4) long chimney Remedy: (1) reducing the amount of air distribution; (2) reducing the height of the chimney; (3) increase the oven temperature; (4) than the exhaust gas temperature low, stopping state under the control of the damper, the damper position switch signal is not fed back to the program signal, throttle check whether the wiring is loose or switch failure.
Steam boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).
Horizontal pressure steam boiler protection 1. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. When the boiler pressure exceeds the vapor pressure protection rating, it is necessary to protect the chain: the furnace is shut down and stop working combustion system; it can change the nozzle, a single stage or two stage combustion, the amount of oil can be adjusted, thereby reducing the pressure, ensure the safe operation of the boiler. 2. Protection of the same pressure level of oil (gas) steam boilers, the use of multiple protection: a pressure controller typically uses two pressure controllers, electromechanical conversion device pressure signal into an electric signal. Its function is different from the high and low signal to the electrical switch, for automatically controlling an external circuit or interlock protection. Common electrical contact manometer and pressure controller can issue an alarm overpressure vapor pressure combustor and cut off, the pressure controller adjusts single or double fire burning fire based on the actual pressure, the pressure controller may overpressure the steam pressure alarm limit is reached close the burner when the limit is reached. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. 2 safety valve safety valve last line of defense to protect the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, exhaust pressure to ensure the normal operation of the boiler.
