Industrial 2 Ton Condensing Oil fired Steam Boiler
Multi-fuel industrial 2 ton condensing fired steam boiler protection water protection Fuel steam boiler: 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. A 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. 2, the 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: imported burner having a flame protection device, 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 failure protection: Under the emergency power supply is interrupted, the boiler shutdown immediately self-locking, 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.
Recently, we learned that the city of Zhangjiakou Yuxian environment departments to carry out a special investigation of coal-fired boilers, coal-fired boilers have complete control of the number of the county, painstaking, and practical coal-fired boiler renovation work to ensure safe and stable environment of the area.
The action focuses on the central heating pipe network has access to the dismantling of coal-fired boiler units, still use coal-fired boiler heating key units of 18 coal quality, coal to electricity station uniform implementation of the 1001 residents of coal-fired heating boilers civilian electric boiler furnace demolition and safe usage, the main city of 39 sets of bath boiler operation of treatment facilities, boiler demolished nine agriculture-related enterprises from coal to gas and gas safety carried out a detailed examination. Unit 4 of the use of substandard coal, the filing be investigated according to law, for gas safety problems 9 agribusiness, notify the county Emergency Management Agency and the territorial towns to regulate the management of its duties, to further prevent security incidents from the source .
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.
Construction of gas industrial 2 ton condensing fired steam boiler steam requirements for the construction of a gas boiler requirements, gas steam boiler installation for the construction of the boiler room have certain requirements, must comply with national requirements in the construction process. Gas and steam 1, the construction of a gas steam boiler room requirements 1) boiler room must comply with the "boiler energy saving technical supervision and management regulations" and "industrial boiler room design specifications" requirement. Gas steam 2) boiler room should have sufficient light and good ventilation, have the necessary antifreeze measures. And boiler room should stay away from schools, housing and densely populated areas. 3) the position should be close to the boiler room heating equipment, in order to reduce head losses and heat loss from the hot oil piping circulating pump. 2, furnace heat carrier device is arranged in claim 1) the sump should be lower than the lowest position of the heat carrier furnace and heat system 1 m, in order to put the net organic heat boilers and systems, sump and furnace heat carrier spacing less than 5 m or separated by a partition wall. It should be fitted with a sump exhaust pipe, which exhaust pipe diameter should be large and specifications than the inflation tube. 2) position of the expansion tank should be higher than the other devices and the piping system, the system must be higher than the maximum bottom level 1.5 m. It should not be installed directly above any one boiler, organic heat carrier to prevent overflow cause a fire. 3) the sump vent pipe, expansion tank, should be connected to the outdoor safety. Can not be mounted on the vent pipe to the valve, to ensure that the tank, the expansion tank to atmosphere to ensure atmospheric pressure operation. 4) the high volume of the expansion tank should be greater than 1.3 times and all the organic heat carrier furnace heat the entire heating systems is at the operating temperature is increased due to thermal expansion of volume. 5) low volume tank furnace heat carrier to be less than 1.2 times the total amount of organic heat. 6) hot oil circulation pump should be at least four weeks for 0.5 m space, and the inspection to ensure the installation routine, the need for maintenance.
