What is the operating principle of the gas boiler

With the launched energy saving policy, the traditional coal-fired industrial boilers gradually being replaced by gas-fired boilers, industrial thermal power field of a revolution is taking place with regard to energy saving. Many users of gas-fired boilers there are a lot of places do not understand, fast Boiler simple for everyone to explain some principles of operations on the gas boiler.

1, injected into the boiler furnace combustion head-mixed fuel and air, the combustion by the ignition device in the head of the full ignition gas furnace, a heating furnace to achieve a boiler, furnace tube effect. Generally begins, a good boiler, the combustion chamber can design a large capacity multi-curve, so that the heating area and stroke to increase the fuel in the furnace body, which can improve the thermal efficiency. Thus, the key gas-fired boiler combustion head, so that the air mixed gas and, after reaching a certain percentage in order to better enable complete combustion of fuel.

Forestry Residues including wood chips, wood pellets, sawdust, bark from forestry operations and processing. Agricultural residues mainly include straw, sugar bagasse, palm kernel shells. All these can be burning fuel for CFB power plant boiler to generate steam or hot water.

Fast boiler is in Anyang City, scientific and technological innovation high bar business, we already heard. After this cooperation really deserved reputation, since the boiler to provide us with a self-running, never malfunction or accident. It comes with a complete remote monitoring service, eliminating our worries. --customer feedback

Boiler furnace pressure increases, steam temperature rises Why? It refers to increasing the absolute value of the negative pressure boiler furnace to increase the furnace pressure. This makes the manhole, inspection openings, etc. through the wall of the furnace tube does not leak into tight places cold air increases, the effect of increasing the excess air ratio of steam temperature similar. Except that the former is organized into the furnace by a hot air preheater, which is not the cold air flowing through the preheater.
