The reasons for failure of imported gas various boiler startup procedure Analysis: Our country is a developing country, is also the world's production of boilers and boiler use than any other country. In recent years, although economic development, people are increasingly aware of the harm caused by pollution, with the implementation of the western development strategy, the environmental protection department of coal-fired boiler renovation project, due to the abundant gas resources, less pollution, so the gas boiler has been It has been widely applied to various industries, not only production, but also our lives. Gas boiler installed in our country, some is imported boilers, but sometimes there will be substandard imported boiler problems, is this why? Qingdao Tsing Yi gas boiler resolve to solve this problem.
Comfortable life of people is inseparable from the northern winter heating various boiler startup procedure, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).
(2) Reasonably carry out various boiler startup procedure blowdown. Boiler sewage is divided into regular sewage discharge and continuous sewage discharge. Regular sewage discharge can eliminate water slag and sediment in the boiler water. Continuous sewage can reduce the salt content and silicon content of the pot water. Therefore, the boiler duty officer should strictly implement the technical measures specified in the technical standards and the operational sub-fields when carrying out the sewage discharge work.
Industry gas various boiler startup procedure room Standard Operating Procedures industrial gas boiler room Standard Operating Procedures industrial gas boiler blast furnace ready to start: gas system: check the gas pressure and the internal combustion engine are matched pressure is normal, not too high or too low, continue under normal circumstances confirm Next. Water supply system: Check the water softening equipment running, the indicators softened water should comply with the relevant national standards. Check level gauge, level indicator switch must be opened, to prevent false water level, to avoid heating the intake air. Check pump for watering, otherwise opening the exhaust valve until the water so far. Stop watering until the water level of 2/3. Close filling pumps and valves. Line pressure: Open inlet and return valve, open No. 1 or No. 2 circulation pump, watching the pressure gauge pressure is normal, the pressure range, and the exhaust air inspection system situation. Electrical system: Check that all control buttons cabinet in an open position, if not open, turn on the switch, turn on the switch to open the order is part of the master switch. Industrial gas boiler flow: System water: Open replenishment pump switch or hand switch is turned on. Another choice is to switch the pump I or II selected pump. (1) Before performing rehydration is necessary to observe whether there is water inside the water softener. (2) while discharging water and discharged from the bottom up high-rise buildings, water supply until the water flow stable and stops. Start boiler front pump (circulation pump), to open the boiler control cabinet, open the internal switch, the cabinet door closed, the circulation pump start switch is pressed, a green light, running forehearth pump (circulation pump), so that a uniform water circulation system. Start boiler: Press the boiler switch red switch button intelligent digital boiler controller, then press the green Start / Stop button, the green light and burner wind, wait a few seconds, the engine ignition, start a normal combustion. Check the record: all the equipment and check the pipes regularly check the boiler. Industrial gas boiler start-ignition combustion: ensure the main power switch, a button to open the burner, fan sweep should begin immediately. Burner ignition failure, fault lights for 20 seconds, press the reset button to restart consecutive three or four ignition failure, successful ignition, should be reported to repair. When the burner is closed due to some failure, each system should be checked to confirm or displacement. After the fault is acknowledged and eliminated, the burner will restart.
