 The optimized utilization of the heating area of ​​the gas-fired steam boiler is based on the principle that the heat exchange in the furnace is proportional to the 4th power of the temperature. The furnace has a large furnace space and a large effective radiant heating surface. The heat absorption of the furnace radiation accounts for the proportion of the total heat absorption. Big. The air distribution in the furnace is uniform, and the temperature field in the furnace is extremely uniform. Especially when the corrugated furnace is arranged near the flame center, the convection heat exchange is more intense. The WNS series steam boiler flue tube bundle is a two-pass, low-velocity design, which effectively reduces the flue gas resistance of the body, and can significantly reduce the operating power consumption of the blower, and the boiler does not require an induced draft fan. The heat dissipation loss is small, and higher thermal efficiency can be obtained than other structu...

  Gas-fired steam boiler refers to a steam boiler heated by gas combustion. The horizontal steam boiler is a shell-type full-wet back flow three-pass pyrotechnic tube structure. The flame burns in a large combustion chamber with slight positive pressure. The combustion heat load is low and the exhaust is reduced. The smoke temperature, energy saving and consumption reduction, adopts the structure of corrugated furnace bladder and threaded smoke tube, which not only improves the heat absorption strength of the boiler, but also satisfies the need of thermal expansion of the heat exchange surface. The exhaust gas temperature of a gas-fired steam boiler is one of the basic parameters of the boiler. Choosing a lower exhaust gas temperature can reduce the exhaust gas loss of the boiler and help improve the thermal efficiency of the boiler. If the exhaust gas temperature of the boiler drops to a sufficiently low level, the superheated water vapor in the flue gas will condense and release...

  Gas-fired steam boiler refers to the principle that steam is generated by heating with water, and the steam generates heat in the furnace, which is mainly operated by heating water. The planning is very user-friendly, simple to operate, easy to get started, and very safe. The boiler is large or small, and the size is selected according to the specific situation. Mainly after heating, the hot water is jubilant to generate steam, and the heat is transferred through the convection method, which continuously circulates in the furnace, and finally exhausts the remaining gas through the chimney. The boiler can also use points to generate heat, and then form power, and continuously produce heat to form a form. The boiler body is the main part of the steam boiler, which is composed of two parts: the "boiler" and the "furnace". The "pot" is a metal container used to hold water. Its function is to absorb the heat energy released after the fuel is burned, so that ...
