used steam boilers with pressure 10 bar

With the development of the technology in textile plant,Boiler have been widely used in textile plant and have improve the efficiency obviously,especially the used steam boilers with pressure 10 bar achieve high appreciation in textile industry.

Boiler furnace excess air control how to adjust? Boiler furnace combustion furnace excess air affects, therefore, how to effectively control the excess air ratio, is one of the prerequisites to protect the boiler reasonable run. Today to excess higher degree of automation of the gas boiler furnace air as an example to explain:

The CFB is a circulating fluidized bed boiler in which a portion of the bed media (sand) is recirculated in the main furnace chamber. Primary fluidizing air is supplied below the bed with sufficient velocity to force the bed media and fuel particles upward through the furnace. Due to an expansion in cross-sectional area at the top of the furnace, the velocity of the existing flue gas is decreased causing sand and particles to drop out of the flow and fall back down the furnace. Some media and particles will continue onward toward the heat exchanger tubes and are collected using a series of U-beams designed to separate particulate and sand from the flow.

March 11, we learned from the Harbin municipal government: Harbin win the 2019 New Blue Sky Battle embodiments released this year, Harbin will be coal-fired pollution control, pollution discharge standards, high Vehicle emission control, comprehensive improvement of urban and rural non-point source, and prohibiting straw utilization as the main direction, precise Shi policy. Strive to the end, so that the sulfur dioxide, nitrogen oxide emissions are reduced by more than 17.6% in 2015 and 20%; concentration of PM2.5 decreased to 52 micrograms / cubic meter or so, and strive to 50 micrograms / cubic meter or less; and more severe reduce the number of pollution days to 21 days or less.

After the proposed scheme, Harbin bulk coal strengthen management and control, strengthening coal quality testing, to improve the sampling frequency. This year will develop clean heating embodiment, the priority development of the city urban central heating; central heating covered areas being difficult to accelerate the implementation of natural gas heating and electric heating, and other distributed clean heating. Unit embodiment "coal to clean energy" should be synchronized removal of coal-fired boiler, gas boiler need replacement after low NOx combustion technology, clean heating rate of 60% or more. City buses, taxis or car clean energy proportion of new energy and strive to reach 94% and 80%. Promote the use of gas vehicles to achieve the national emission standards for six. Six to stop selling below the country's gasoline and diesel. Establish responsibility dust control system, built-up areas prohibit the construction site mixing of concrete, mortar and use of bagged cement 9 city and county (city). Under the premise of protecting people's livelihood, heating boilers should be relatively conducive weather conditions during the pollutant dispersion from the oven, in the same area by different heating boiler early in the evening three periods of peak load shifting from the furnace.
