Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ steam boiler check valve should be in the closed state industrial hot water boiler manufacturers circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump
Multiple protection devices take you through the oil steam boiler oil steam boiler water level protection, boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. Steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection, having imported burner flame protection means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
The oil gas power plant boiler has low NOx emissions in the flue gases. In the combustion zone of the boiler, the membrane wall is spiral wound, utilizing smooth-bore tubing. This inclined-tube arrangement reduces the number of parallel paths compared with a vertical-wall arrangement and therefore increases the mass flow of steam/water mixture through each smooth-bore tube. The development and realization of high efficiency methods for burning the oil and gas fuel in our power plant boilers make it possible to save fuel and reduce the emission of harmful substances while meeting rigorous safety requirements.
First Affiliated Hospital of Bengbu fully implement the national environmental protection policies, strict screening of clean boiler as the supply of medical supplies disinfection and ward heating equipment. Fast boiler with its focus on research and development of clean-type gas boiler two decades of experience in the industry favored. The partnership, to provide fast boiler First Affiliated Hospital of Bengbu Medical College, a WNS20-1.25-YQ one condensing steam boiler, in terms of design, manufacture, installation and other aspects of strict checks to enhance the thermal efficiency of the boiler as well as truly Energy saving and environmental protection.
