How to choose Gas fired Boiler

Buying boilers to provide hot water is a good option for hotels and hotels that consume a lot of hot water. If you use your own gas-fired boiler not only convenient and quick, but also to a great extent to achieve the purpose of saving expenses. So how do these operators choose the more suitable products among the various kinds of gas-fired boilers in the market?

1, because of the importance of gas-fired boilers, the choice of materials is good, so consumers will not pay too much attention to the price in the process of selection. Instead, the cost-effectiveness of gas-fired boilers will be taken into account, that is to say, good quality should be chosen beyond the price, and only the products produced by manufacturers that have high procurement standards for materials such as steel and accessories are good enough.

2, choose manufacturers with good qualifications if consumers want to buy a satisfactory gas-fired boiler then must choose those qualified manufacturers. The manufacturers with good qualifications have a long production history and a more complete range of boiler products sold on behalf of the manufacturers, and the basic guarantee of these is that the manufacturers can have a relatively complete production line and a standard and reasonable management system.

3, whether the quality of after-sale service is good or not is directly related to the operation effect of the boiler if the after-sale service is good for the buyers of gas-fired boiler. Therefore, in the process of selection, we must choose those manufacturers that have guaranteed after-sale service for gas-fired boilers, because the contents of the complete after-sales service include a series of important work contents, such as installation and commissioning of boilers, and so on. Only by doing all this well can the boiler get into a good state of operation.

Hot water boiler heating industry is our essential equipment, gas high efficiency atmospheric hot water boiler water provided by the party fast flotilla, high thermal efficiency direct savings on fuel costs of inputs for our company, the intelligence facilities let the boiler run more convenient and effective to reduce the labor intensity of fireman people. --customer feedback

Problems and solutions smoke flue gas condensation problems outer fuel gas steam boiler flue gas circulation technology for low NOX combustion, but since the flue gas circulation method requires an outer part of the fumes at reflux for mixing fuel gas with the cold air of the steam boiler, after mixing the temperature will drop sharply, resulting in condensation. Even at reflux smoke and cold air is mixed at a timely discharge of condensate, but due to the combustion air humidity after mixing is still saturated, still occur in the pipeline again condensed before entering the combustor. Therefore, it may cause internal main burner and blower moisture, water, and even lead to serious consequences electrical short circuit, corrosion. Affect the normal operation of the main burner and blower, shortening the life of the burner, or even damage the burner. So, to solve the problem of fuel gas steam boiler flue gas condensation on the external flue gas recirculation very important to the development of low NOx combustion technology. Common external flue gas recirculation system for low NOX combustion, flue gas condensation problem can be solved usually by reflux smoke, cold air, or a mixed flue gas is mixed with the cold reflux heated. Of course, how heated? How much is heated to a degree?, Would require careful fine. Because the temperature is too low, flue gas condensation problems are not resolved, the temperature is too high, the burner will damage; the temperature of the heating process control is very important. The heating source may be a flue gas waste heat, waste steam, or other auxiliary heat source. Considering investment costs and operating costs, it is recommended that: the use of boiler production of high-temperature water / steam indirect heating combustion air, solve the problem of condensation after mixing combustion air and flue gas with the most simple way. Of course, it is heated to reflux or flue gas mixture according to the situation. The heating temperature by controlling heat transfer equipment hot water / steam regulating valve to control.

As low boiler heat load case, the flow through the small steam, but the steam turbine requires the corresponding low temperature, generally do not result in too high wall temperatures of the superheater platen, use of time if a desuperheater adjusting the steam temperature control, since the flow of steam after desuperheating water injected into long, the flow rate is very low, the boiler outlet steam temperature the reaction very late pure, easily lead to low-temperature steam, and water may form a plug in the serpentine tube portion. In this case it should be disposed near the secondary steam desuperheater outlet, water in minor amounts, the fine steam temperature.
