When coal-fired vertical cross tube boiler design chemical engineerings, which need to use technology

Coal-fired boiler is an important step to promote the process of China's energy-saving and environmental protection, many cities are very encouraged coal-fired boiler reconstruction project, giving premium policy, depending on the duration and scale of reform.

Pressure vertical cross tube boiler design chemical engineering plate and the actual operating pressure is different. Nameplate pressure hot water boiler is a boiler manufacturer according to the national standard GB3166-82 series hot water boiler product design parameter, which represents the maximum working pressure hot water boiler. The actual working pressure hot water boiler is determined by the operating pressure of the circulation pump, which is generally lower than the pressure plate. To prevent the boiler water, water vaporization occurs, the pot should be maintained to some extent a pressure above the saturation pressure at the corresponding temperature. 3, Rated water temperature: is the maximum allowable under the normal operation of the water temperature.

Shutdown operating steam vertical cross tube boiler design chemical engineering steam boiler shutdown is divided into two kinds, the temporary shutdown (within three days), complete shutdown (shutdown or overhaul more than three days). A steam boiler temporary shutdown: 1, according to the actual situation, the appropriate weakened combustion, stopping the steam, followed close blower, Fan, grate steam sector. 2, until the furnace temperature dropped to fire when the pressure starts 400 ℃, covering the layer of wet combustion of coal seam, close the damper, coal down the shutter, open the exhaust valve exhaust. 3, the boiler water level to be adjusted to a vapor pressure drop 0.15MPa when the maximum operating level, closing the main valve until the furnace temperature dropped off when the main power 200 ℃. 4, run the table in the line of steam boilers make a record, do the work of changing of the guard. 5, steam boiler pressure during the fire need to have someone on duty to prevent coal combustion and boiler water and other accidents. Second, the complete shutdown steam boiler: 1, the steam boiler is stopped an hour earlier coal supply steam, the steam to be sequentially turned off after stopping blower, Fan, grate. The excess coal in the coal hopper picking out, open grate, coal and slag in the furnace cleaned up. 2, adjust the boiler steam boiler water level to the maximum working level if the shutdown to one week, open the exhaust valve, the pressure to be reduced to 015MPa, the main steam valve closed. 3, steam boilers quickly opened if the maintenance or long-term shutdown, the pressure drop 0.4Mpa all drain valve, drain the boiler water, dried using waste heat boiler and do respond to treatment. (Note: You must turn off the furnace temperature drops after about 200 ℃ can turn on the water). 4, turn off the main power shutdown, make relevant records on the operation table boiler.

Recently, the Anyang city government released the 2018 benchmark of scientific and technological innovation of enterprises citation, to be commended and encouraged Anyang nine local enterprises. I company with a solid technology skills, steady pace of development and constantly aggressive determination to win awards municipal government. As a high-tech fast square vertical cross tube boiler design chemical engineering manufacturing enterprises, while maintaining infrastructure, adhere to scientific and technological innovation path of development, follow the development of high-quality, strengthen management, attention to restructuring, rushed development, highlights frequent, becoming the city's technology and industrial double front of the vanguard, Anyang City for a number of honors in the country, enhance the technological competitiveness of the city.
