4 7 mw hot water fire tube boiler

SOPs electric steam 4 7 mw hot water fire tube boiler 1, the electric steam boiler before opening the valves to confirm the correct position, the water supply, power supply is normal. 2, press the power switch, power indicator light, alarm controller (due to lack of water in the boiler) at the same time the pump starts to operate, the controller stops the alarm after replenishment to low water levels, the electric steam boiler running indicator lights, automatic replenishment High Level , water pumps stop. 3, replenishment to the water level, when the furnace pressure is low, electric heating tube starts automatically. 4, the electric steam boiler pressure reaches the set value, automatically stop heating, steam valve is opened at this time can, using steam. 5, steam is used, the furnace pressure drop, when the pressure dropped to the lower limit set value, the heating is started automatically. 6, when using the steam oven water level falling, when the water level falls below the low that start the pump, supply water to high water level to the furnace. 7, when the water level is below the low level, and supply system is not functioning normally, 10 seconds after the water level does not reach the low water level electrode, heating tube heating was stopped, as the water level continues to fall below the low water levels electrode, alarm and shutdown protection controller. 8, off. Electric steam boiler work is finished, press the "Power" switch off the power, the power light is off, turn off the power switch. When the pressure gauge to be reduced to 0.15 ~ 0.1MPa, the blowdown valve is opened for discharge, the inlet valve closed.

Gas 4 7 mw hot water fire tube boilers can bring a lot of convenient place for industrial production and people's lives, it is one of the major energy equipment. Long-term use down the gas boiler, there will inevitably be a failure will inevitably occur solidification scale, rust and corrosion phenomenon, which affects the useful life of the boiler. But if it is to know how to carry out maintenance, perhaps the situation is quite different, these problems may not occur, boiler service life can reach 10 or even 20 years. Here, we have to teach you some tips on caring for a gas boiler, so that we make better use of gas-fired boiler.

According to our learned Wenzhou Municipal People's Government on February 12 issued a notice "Wenzhou Blue Sky win the Battle of action to implement the program (draft)", the details are as follows.

Accelerate the implementation of the relevant arrangements for the deployment of national, provincial and develop natural gas and other clean energy. According to Yi gas of the gas, the electric power should be the principle, and actively guide enterprises to implement energy clean energy alternative, 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, to further improve the urban and rural distribution pipe network construction , the city's natural gas consumption reached 570 million cubic meters, the proportion of non-fossil fuels in total energy consumption to reach the provincial requirements. Orderly development of hydropower, safe and efficient development of nuclear power, optimizing wind energy, solar energy development layout, local conditions to develop biomass energy, geothermal energy and so on. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects. Continue to implement the priority generation and purchase of electricity system to ensure the city's renewable energy generation full protection of the acquisition.

Strict new coal project access, the implementation of the reduction of coal instead. According to the State to win the Battle of the sky three-year action plan calls for no new 35 steam tons / hour high-polluting fuel boilers. By 2020, the city's coal accounts for the proportion of total energy consumption fell to 42.8% or less, the city's total coal consumption decreased by 5% compared with 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal in 2020, the city's electricity and central heating coal proportion of total coal consumption reached provincial requirements. Continue to promote alternative energy coal and oil, replace reached the provincial requirements.

For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity in the region rely on new clean energy generation and transmission to meet outside the main electricity consumption. In the premise of protecting the power system security and stable operation of 2020, to accept the outgoing power levels to at least 38%.

Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to the National to win the Battle of the sky three-year action plan calls for phasing out the 10 steam tons / hour and coal-fired boilers, the county level and above urban area basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment, etc. facilities; basically eliminated the city's 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers; 35 steam tons / hour and more polluting fuels and energy-efficient boilers to complete the transformation of ultra-low emissions; low nitrogen gas boiler basically completed the transformation; city built-up area of ​​biomass boilers implement ultra-low emissions transformation.

Oil-fired 4 7 mw hot water fire tube boiler oil-fired boiler flameout flameout how to do, although rare, but it does not mean that will not happen, when it stalled how to do it? Once the flame must be immediately cut off fuel supply to the furnace, the air supply closes the solenoid valve (oil supply and return), and then close the fuel supply valve of each burner operation occurs. Operation action to be fast, so as not to continue or resume the supply of fuel, causing a risk of malignancy. At the same time, to identify the cause of the boiler flame, troubleshooting discovered, and then start doing the preparatory work. Before you start, should strengthen the oil-fired boiler ventilation, purge, purge time is more than 5min, then procedures ignition. When the ignition is prohibited sent directly to the high temperature furnace fuel ignition without using an ignition device, in order to prevent dangerous accidents furnace. If due to fan failure caused when the flame, should quickly close the fuel supply line valves each, paying particular attention to the valve not tightly closed due cause fuel leakage. Meanwhile, according to emergency shutdown processing method for ventilating and purging of the furnace and the flue. After the fan resume operation, then step ignition. If only the burner flame, only close the fuel supply valve of the burner, the burner off damper small, identifying and troubleshooting, and then re-lighting the ignition process. Quickly and correctly treated, in order to ensure the safe operation of boilers, of course, if you are always welcome to your online consultation to have any ambiguities about the oil-fired boiler.
