singapore first boiler in maritime industry
Boiler excess air ratio increases, why steam temperature rises to follow? Excess air ratio increases singapore first boiler in maritime industry (originally assumed optimum excess air ratio), the temperature drop in the furnace, the heat radiation wall absorption reduction, the furnace exit gas temperature decreased slightly. Since the magnitude of the amount of smoke increases, the speed increase of smoke, the heat transfer coefficient of heat transfer temperature difference is greater than the rate of increase is reduced, so that the increase in heat absorption of the superheater. Since the increase in the amount of exhaust gas temperature and flue gas, q2 is increased, reducing the efficiency of the boiler, in the case where the same amount of fuel. Reducing evaporation, and therefore, the steam temperature rise. Generally, the excess air coefficient of 0.1 for each increase, steam temperature rise 8 ~ 1O ℃.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new singapore first boiler in maritime industry equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
When gas heating singapore first boiler in maritime industry maintenance methods outlined (a) gas heating boiler more frequently compared to winter season, then the application will not be need to be simple maintenance, the maintenance of gas heating boiler method, what does ? The following small series in which the first a dry regimen simple example set forth. Three methods of dry Maintenance method: (1) After heating boiler shutdown, we must first produced during the operation dirt clearing is completed, in the process should have a tubing connections with the outside world were cut block. (2) shutdown a long time, to the boiler rust maintenance, troubleshoot and repair their accessories in the furnace heating boiler and flue can be implemented dry lime boiler maintenance. (3) the use of a desiccant boiler during use to pay attention to the amount of control, but to do the water system of boiler and Flue Gas System and isolation to protect the outside world, so as to avoid the outside world into the water, causing the drying effect is reduced. In addition of course, there may be other details of the work and methods of dry maintenance, which requires the actual situation, selective use, to ensure maintenance of effect in a reasonable manner presented.
Boiler blowdown: First, the function and purpose of the singapore first boiler in maritime industry blowdown is the object of the sewage drain pan high salt concentration water, boiler water and corrosion and precipitate the salt content in boiler water is maintained within a prescribed range, to reduce the expansion of the pot and the water bubble layer, thereby reducing the salt content and humidity of steam to ensure good quality of steam. At the same time, the sewage may eliminate or mitigate fouling in the evaporator by the surface of the pipe. Second, the ways in which the boiler blowdown Boiler Blowdown points on a regular basis sewage and continuous blowdown two kinds. Continuous blowdown: also called surface discharge is continuously draw off a portion of the boiler water, the purpose is to let go of the salt was dissolved in water and the pan pot water surface float. Regular Drainage: emission time per predetermined time, the main purpose is to let go of the precipitated water boiler slag, of course, with a pan of water soluble salt. Its emissions group should be more precipitation the lowest part of the boiler slag. Third, why the installation of boiler blowdown boiler blowdown water introduced into the larger container expansion down, the vessel is called blowdown. With different ways, it can be divided into two kinds of a given row and even row. Platoon for working medium and heat recovery. Because a given row of sewage water and sewage indefinite periods of time, now we can not be recovered. Given row down by expansion, an upper steam into the atmosphere, the water from the lower into the trench, it is to reduce noise and ensure safety.
