Hot Water Gas Condensing Boiler

The reason gas steam hot water condensing boiler popular what are gas steam boiler works and composition of what is? You know, friends do? The following is a gas steam boiler manufacturer's technical staff to explain, I hope for your help. Gas steam boiler is a thermal energy conversion device, which uses natural gas, LPG, city gas and other gaseous fuels as a fuel, the combustion heat released in the furnace, heating the water in the pot, and it was evaporated into steam. The gas fuel boilers (pan) of the combustion energy released continuously heat the water temperature, to produce pressurized steam, the boiling point rises with increasing pressure, the expansion seal pot, the internal pressure of the steam generated is limited to form a thermal energy (strictly speaking, the boiler steam drum by constant pressure heating of the water formed, so that saturated water evaporated) as an energy resource. Gas-fired steam boiler furnace mainly from the shell and the two bodies and ensure a accessories, auxiliary equipment instrumentation, automatic control and protection system of continuous safe operation of its composition. Gas boiler steam boiler is a boiler, with a cold crucible. Pyrotechnic gas boilers have two return tubes arranged in the left and right sides, the front of the cigarette before the folding drum. Between the drum and the lower tank, having a lower tube and a water-cooled manifold, a combustion chamber to form a frame. Top drum having a vapor separator for reducing the water vapor. Gas heating boiler body surface is a lower steam drum, the water-cooled manifold and fireworks tube. Very energy efficient in terms of gas-fired boiler. His high costs in terms of fuel costs and liquefied petroleum gas and electric boilers. Gas-fired steam boiler is a protective boiler. In use, dust and gas will damage our health. Natural gas will not have this problem. High thermal efficiency gas furnace steamer, can reach more than 90%! The key is his long life, he uses dye is very clean, it does not produce dust and soot when burned in a furnace, so his life much longer than other boilers. In the development of the boiler, he is moving in environmental protection, energy conservation and development goals.

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.
