coal oil pellet industrial steam boiler water and fire tube
Operation of a gas boiler gas boiler in Henan related to maintenance, the ignition operation, fire, shutdown and some other operational measures: First, the gas boiler maintenance Henan, operating procedures should be required to carry out tests on the gas transmission main boiler protection devices, ensure that the main protection correct action. Second, the ignition process Henan gas boiler, fuel pressure, fuel temperature, steam pressure atomization, atomization steam temperature and other parameters must meet the requirements of operating procedures, good place to observe oil gun fire, fire detection return to normal, prohibit short-energize inspection signal forcibly put into the oil gun running. Single oil gun when the flow is greater than 0.65kg / s, exit the gun should be run immediately. Third, observe boiler ignition temperature rise rate of fire smoke significantly Pianman furnace flue gas temperature of the main steam temperature, steam pressure rises when the main, the case of smoke or boiler ignition temperature did not rise immediately to check the opinions of the oil gun, if No fire was found after the fuel into the furnace, emergency shutdown, re-ventilate the furnace purge Do not allow to run into the boiler ventilation oil gun. Fourth, note that starting mill to check whether the subject returns normally coals, coal mill outlet temperature of greater than 70 deg.] C line is allowed to increase the amount of coal (three grinding mill operation start of the fourth stage, the coal mill outlet line than 80 ℃ temperature allowed to increase the amount of coal, to prevent excessive vibration furnace). Full stop before the gun when the present discharge amount of coal is increased 5.0kg / s or more. 6.3.5 Operating Henan gas boiler, "furnace black", "lose the protection of the main fuel" must be put into operation as required operating procedures. In case of a fault protection device itself appears to be temporarily out of operation, to be approved by the competent manager or chief engineer before implementation. "Furnace black", "main fuel unprotected" means the period out of operation, priority monitoring attendant to furnace pressure, the oxygen, the main steam temperature, the main steam pressure and other parameters, and through the furnace of fire industrial television monitor, and if found hearth fire, emergency shutdown. Sixth, Henan gas boiler normal operation, the fuel system and oil spare gun good condition, found that boiler combustion instability immediately put oil combustion. Seven, after Henan gas boiler fire, into the oil gun is strictly prohibited without the operation of the boiler ventilation. Eight, gas boiler has confirmed the fire, when the MFT is not operating, emergency shutdown, and check that the two primary air fan, 4 mill, 16 oil gun has stopped running. Back nine, Henan gas boiler trip or normal shutdown to be purged immediately ventilate the furnace, the furnace unburnt coal dust and combustible gas pumped in a timely manner. And promptly shut down the boiler supply and return oil total gate manually to prevent leakage of fuel oil gun into the furnace. Ten, Henan gas boiler shutdown purge gun ban mill and pulverized coal into the furnace exhaust.
Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of 11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.
The 5 ton natural gas boiler used in the tea factory is the wns series oil and gas fire tube boiler. It has long been known that where a supply of steam is required for process work in any industry. In the tea industry, the 5 ton wns series natural gas coal pellet industrial steam boiler water and fire tube is used for heating the air required for the tea dryers and withering lofts. WNS series oil gas steam boiler is horizontal fire tube boiler. The boiler has steady temperature and high coefficient of heat transfer. And adopts specially designed combustion chamber for a better combustion efficiency. Advanced burner and proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process. Electric control cabinet contains some buttons of burner, feed-water pump etc.
Evaporation capacity is below 4t/h and 4t/h boiler. Check water level gauge, steam pressure gauge, feed water thermometer, exhaust thermometer, steam flow rate calculation. Oil temperature, oil pressure, oil level indication, oil quantity calculation, furnace outlet smoke temperature indication. The boiler should also have oxygen content of flue gas, negative pressure of furnace, economizer inlet and outlet water temperature indication.
