Such diffusion combustion combustion method that is not pre-mixed combustion method, but the mutual diffusion of the gas nozzle opening, and burned. The advantage combustion stability, simple structure gas appliance, but the flame longer prone to incomplete combustion, heated area carbonation. Such premixed combustion part of the air before combustion that is part of the pre-combustion air is mixed with the gas (primary air excess coefficient between 0.2-0.8), oil-fired boiler supplier, and then burned. The advantage is clear flame burning, high-quality oil-fired boilers, combustion enhancement, Hubei oil-fired boiler, high thermal efficiency. But unstable combustion boiler fuel supply, the control of the primary air and combustion components higher. Gas burners generally burn more such manner. When the boiler normal shutdown, the general should be reduced boiler load, then press the shutdown switch, press the boiler automatically shutdown. Start the pump inlet to high level until the boiler pressure drops after 0.3Mpa flushing water table and sewerage operations, and finally close the main steam valve, cutting off power control cabinet, wipe equipment, clean up the environment and health; To turn on the water, the water temperature should After less than 70 ℃, it can be carried out. Supply of oil-fired boiler, oil-fired boiler Hubei, lofty boiler provided by Xinxiang City Boiler Equipment Co., Ltd. lofty. Supply of oil-fired boiler, oil-fired boiler Hubei, ambitious boiler Xinxiang City Boiler Equipment Co., Ltd. lofty (www.hnxxydgl.com) (www.ydglsb.com) this year introduced a new upgrade, the above picture is for reference only, please dial this page Phone or pictures on obtain the latest information, contact: Xu Jinlong.
