As environmental pollution intensifies, boiler equipment, which is a major source of pollution, continues to enhance its environmental performance. Boiler flue gas purification system including dust removal, desulfurization, denitration equipment, their role is to remove the boiler flue gas entrainment of solid particles (fly ash), sulfur dioxide, nitrogen oxides and other harmful substances, in order to improve the atmospheric environment.
Boiler gas supply system generally supply duct inlet means, gas piping system and a boiler room emission purging conduit and other components. Some requirements are as follows:
1) from the boiler room to the gas pressure regulating stations gas pipeline (gas introduction tube boiler), except when special requirements need to consider the production of the outer gas tube double, generally single gas pipe. When gas double pipe, each pipe capacity by gas boiler 70% of the total gas consumption is calculated.
2) When the intake pressure regulating device in more than 0. 3MPa, and larger than the surge, large noise may be generated, in order to avoid the noise transmitted along the duct to the rear gas boiler room, the regulator means 10 to suitable 15m section of pipeline laid underground to take.
3) gas is introduced from the outside manifold gas boiler room, the total should be installed at the inlet shut-off valve, a gas-flow direction, the valve should be installed before the vent pipe, and a sampling port mounted in the vent pipe should be installed after the purge valve joints.
Industrial gas boiler introduced: industrial gas combustion boiler quick a horizontal three-pass fire tube boiler furnace using offset wet back structure, high temperature flue gas flushing sequentially the second and third return pipe tobacco, and a rear chamber by the smoke. chimney into the atmosphere before and after the smoke with movable cover boiler, the boiler easy maintenance. boilers with good technical performance burner using combustion automatic ratio adjustment, automatic adjustment of water supply, the program start and stop, automatic operation and other advanced technology, and having a low water level and low level alarm, high vapor pressure, flame automatic protection function. the boiler has a compact, reliable, simple, quick installation, low pollution, low noise, high efficiency.
Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas boiler governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.
In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.
To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.
