About tempering gas boiler and fire off phenomenon have what? When the gas boiler during combustion operation, there will be some anomalies, which will directly affect its operational status, such as the device will appear as tempering and fire off such a phenomenon, the negative pressure inside the gas boiler will suddenly become valleys, and the flame color will change ensued, which, we must find the cause and solution to the problem, in order to avoid the risk of accidents.

Recently, the vice governor of Henan provincial government, Comrade He Jinping and his party, accompanied by the main leaders of Anyang City, to visit our company for investigation and guidance. Accompanied by the Group Chairman Mr. Lu Haiqing Luhai Gang and Mr. President, R & D Center Exhibition Hall and cleaning boilers Laboratories plain plant were overall investigation. We came to the R & D Center Exhibition Hall, the research group members have been attracted to the science of video technology products, stop listening to the president on corporate R & D, manufacturing scientific products situation report.

China's industrial boilers with coal as the main fuel, with a small stand-alone capacity, divided Maldistribution characteristics. Due to the low degree of automation equipment and long service time, low operating efficiency, pollution is also very serious. Survey results showed that nitrogen oxide emissions from industrial boilers account for 15% to 20% of the total emissions of nitrogen oxides, grate is an important part of industrial boilers, and thus emissions of NOx can not be ignored.

872, should pay attention to the use of pressure hot water boiler: the world since the 1970s, pressure hot water boiler, especially in the northern region will get extensive application in China. Its popular not only because of low cost, easy to manufacture, more simple management, operation and safety features in its. Because of pressure hot water boiler has been widely used in various industries, it is especially important to use precautions.

Plant Engineering | Five common steam line sizing errors

May 01, 2005 · The resulting steam would occupy a volume of 6.7 ft3/lb. For acceptable velocities this pressure setting would require a 4-inch steam line (Sch. 40). However, if the same boiler is set at 200 psig, steam tables show the volume reduces to 2.14 ft3/lb, requiring only a 2-inch steam pipe. Look at the economic impact.

Stanley Steam Car Boiler

The 20 horsepower cars made up until 1917 used a 23" diameter boiler that was 14" high. With the introduction of the Model 735 car in 1918 the boilers were 23" in diameter and 18" high. All 30 horsepower rated cars including the Stanleys famous Mountain Wagons used 26" diameter boilers that were 16" high.

equalizer pipe. (normally a 2 inch diameter pipe joining the steam header to the return line near the boiler) helped prevent water from backing out of the boiler by ensuring that the steam put equal pressure on the supply and return side of the boiler. The equalizer pipe looks like a short circuit between the supply header and return pipe.

Steam Pressure Reduction: Opportunities and Issues

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boilers net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
