Secondly, we must pay attention to the air pressure of the gas industrial boiler yellow flame. When the air pressure in 0.05-0.1MPa, do not forget to issue replenishment, sewerage, water supply system and check the test device to send weapons; when the pressure rises to 0.1-0.15MPa when the need to gauge the trap cleaning ; when the pressure rose to 0.3MPa, to "fire load / small fire" knob to "fire" to strengthen combustion; when 2/3 gas boiler pressure goes up to the rated pressure, you can begin to warm the pipe and aspirated operation, and at the same time pay attention to slowly open the main steam valve to avoid water hammer phenomenon, resulting in adverse effects.
As we all know, the boiler fouling, not only difficult to clean, but also have a significant negative impact on operating efficiency, serious and even lead to boiler damage.
Phase out coal-fired industrial boiler yellow flames, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.
The phase-out of coal-fired boiler from the following three points.
First, the coal-fired boilers carry out a comprehensive investigation work.
Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.
Second, carry out the phase-out coal-fired boilers.
Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.
Third, strongly promote the boiler-depth treatment.
Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.
