Many provinces in the western region are located in the plateau, low atmospheric pressure, relatively thin air, so the fuel combustion process and burner selection methods compared to the plains have their own special characteristics. Compare the technical requirements of boiler gas burner, except for the structure, the rest are directly related to the low air pressure, as follows
1.low air pressure affects the density of the gas mixture, so that the range of the gas jet changes, which in turn affects the flame shape and size and the matching problem of the furnace chamber structure.
2.the air density in the Xining area is 1/4-1/3 lower than the standard state, which generally exceeds the adjustment range of the burner air-fuel ratio, and the combustion conditions are unstable.
3.due to the instability of the combustion road conditions, directly affecting the rated output of the burner.
4.incomplete combustion under the conditions of oxygen deficiency, so that the harmful components in the flue gas increased.
