horizontal gas fire tube boiler manufacturer

Hot water horizontal fire tube boiler manufacturer in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

Gas-fired steam horizontal fire tube boiler manufacturer safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.

Increase productivity horizontal fire tube boiler manufacturer system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

Gas-fired steam horizontal fire tube boiler manufacturer has a positive effect on sustainable development: the increasingly tense in recent years as the price of coal and coal supply more of our day to rise, more and more companies turning to heating gas heating from the traditional gas heating, gas-fired steam boiler heating for its environmental protection, energy conservation in the country has been more widely used, in particular, focus on the most popular heating gas boiler room. From an economic analysis using gas steam boiler operation point of view, generally more than 5 years of small and medium sized gas steam boiler no longer have the value of the Burning gas. Many of our cities in a few years ago began to control the construction of small and medium sized gas steam boiler, the boiler was included within the scope of the demolition basically a longer useful life or the furnace has been out of the product. Be evaluated by the thermal efficiency of a steam boiler and to detect the remaining useful life, with the new gas boiler economic comparison can be seen, simply to change the method of gas fired boilers have undesirable manner by replacing the burner. Gas-fired steam boiler is the ideal replacement for gas steam boiler. Although the thermal efficiency of the fuel steam boiler was also higher, but the smoke pollution in the atmosphere is much larger than gas-fired boiler, steam boiler fuel and there are also issues related to oil transportation and storage, it lost the advantage of long-term development. Gas steam boiler and a steam boiler with gas as compared to the obvious advantages: Since the gas in the ash, sulfur and nitrogen-containing volume is lower than the content of the coal, the amount of dust generated in the flue gas after combustion minimal emissions the flue gas is easier to meet the standards required by the state of combustion equipment, the use of gas-fired boilers can greatly reduce the pollution of the environment. A high intensity gas furnace volume the hot steam boiler, due to the small smoke pollution, a strong convection tubes from corrosion and slagging, heat transfer effect, a large amount of combustion gas triatomic gas radiation, and low exhaust gas temperature, make thermal efficiency improved significantly. Aspect of saving the equipment investment boilers, gas steam boiler furnace may choose a higher thermal load, thereby reducing the volume of the furnace. Heating surface due to contamination, slagging, there is no problem of wear, can use a higher-speed cigarette, to reduce the size of the convection heating surface. Reasonable arrangement convection tubes, so that the capacity of the gas boiler with gas boiler more compact structure, small size, light weight, reduced investment in equipment significantly. Why is it so popular environmental protection boiler
