Boiler and steam conditions What? 1) normal horizontal straight tube boiler plant, combustion stability. 2 vapor pressure) and steam the furnace tube is slightly lower than the vapor pressure of main steam 1 to 2 psig pressure in the boiler; Table 2-3 high pressure boiler. This is to avoid excessive pressure is not very stable Ambassador temperature steam into the oven from the start a lot of steam main pipe, causing the steam with water, boiler water level impact and instability. 3) steam temperature and steam oven should be slightly rating, and specific values should be considered equipment conditions. This is to avoid over-temperature and rapid decrease due to the steam or steam temperature steam main pipe and the furnace for the force with water (4) drum water level is maintained low level. This is because in order to avoid contact with the steam and the water level rises over the water load (5) steam quality (including Na +, or the amount of salt content) qualified. This is to avoid vapor and steam oven failed to affect the quality of the mother pipe steam quality.
Low nitrogen horizontal straight tube boiler three points, it will not be duped poor transformation of the low-NOx combustion technology from developed to practical application, has been recognized by many professional organizations, low nitrogen transformation technology also will become more mature.
