What is the state of a burning oil-gas boiler after it is put out? How to judge whether the burning oil and gas boiler is extinguished? Oil-gas boiler manufacturer-gas-fired Fangkuai boiler for you to introduce in detail: The indicator value of the negative pressure gauge in the furnace of oil and gas fired boiler suddenly increases, the furnace blackens, the flame can not be seen from the fire hole, the combustion sound in the furnace disappears, the flame monitor sends out the fire extinguishing signal. Air temperature, air pressure drops sharply, water level drops first and then rises, etc., all of which are extinguished. Due to the auxiliary engine accident caused by the quenching, such as induced fans, blower power interruption, there is also an accident signal; if the fuel supply interruption, the boiler fuel or gas pressure is reduced to zero.

Off state of the oil-fired boiler and approach the customer Q: oil-fired boiler flameout what state? How to determine whether the fuel gas boiler flameout it? Henan A fast boiler Company: Table fuel gas boiler furnace pressure instruction value suddenly increases; the furnace black, can not see the flame hole to see the fire; sound disappears combustion furnace; issued extinguishing the flame monitor signal; temperature, pressure abruptly fall, after the water level decreased and then increased, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply is interrupted as a result, oil-fired boiler fuel pressure is reduced to zero. If only a single burner flame, the furnace may also occur flame center deflected off the burner pressure changes; fuel supply is interrupted as a result, the extinguished burner pressure or hydraulic indication may drop to zero, while the other run burner fuel, gas pressure. After this occurs, must be timely treatment to ensure safe boiler. Customer Q: oil-fired boiler flameout, how can I deal with? Boiler Company Zhoukou City lofty Answer: Once a flameout must immediately cut off the fuel supply to the furnace, close the solenoid valve supply (supply and return oil), and then close the fuel supply valve in each operation of the burner. 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 starting, we should strengthen 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, simply close the fuel supply valve to the burner, off throttle small oil-fired boiler, to identify and troubleshoot, and then re-ignition process the ignition. Be sure to quickly deal with properly in order to ensure the safe operation of the boiler.

What problems should be paid attention to in maintenance Electric normal pressure Boiler

Nowadays, advanced electric atmospheric pressure boilers need to be used in industrial production as well as in daily life. However, the electric atmospheric pressure boiler is a highly operational mechatronics equipment, such as customer inspection, maintenance is not timely will result in equipment line aging, equipment oil circuit and oil pump wear and so on. Therefore, users need to pay attention to the maintenance of equipment when running boilers, then, what problems should users pay attention to in the maintenance of electric pressure boilers with good performance?

1, pay attention to stop furnace detection electric atmospheric pressure boiler in the maintenance, users should let the equipment according to the normal shutdown procedure operation to achieve slow cooling, at the same time, Users should use pot water circulation and furnace ventilation to gradually reduce the temperature in the pot and furnace. It is worth noting that when opening the door hole of the equipment, users need to pay attention to preventing the burning of steam, hot water and flue gas in the boiler.

2, note that when users maintain the insulation, the combustor and flue of the detected atmospheric pressure boiler should be separated from the total flue or the other running boiler flue. The test results are as follows: (1) the combustor and flue of the tested atmospheric pressure boiler should be separated from the main flue or other running boiler. And the flue gate should be closed tightly, and in the partition after ventilation. In addition, the blind plate used in equipment partition should have sufficient strength and hardness to avoid being bulged by high pressure medium in the operation of electric normal pressure boiler, and the partition position should be clearly indicated to avoid confusion.

3, note that the user must completely cut off the connection pipe between the vessel and the gas equipment, especially to the combustible and toxic medium equipment before the inspection of the atmospheric pressure vessel is carried out by the user of the equipment container. In addition, the equipment container not only needs to close the equipment valve, but also needs to use the blind plate of the equipment to close the valve so as to prevent the gas leakage into the container and cause the fire explosion or poisoning accident of the valve so as to cause the combustible or toxic gas to leak into the container.

The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
