Qinhuangdao City Funing District Branch of Ecological Environment Agency organized the key enterprises responsible person within the jurisdiction of the boiler demolition, renovation work will hold a special schedule. The meeting stressed the need to vigorously promote coal-fired, gas-fired boiler demolition, renovation work progress, continued to improve ambient air quality.
At the meeting, staff of the Office of atmospheric area of the current coal-fired, gas-fired boiler demolition, renovation progress has been informed. Up to now, boiler demolition and reconstruction of the region involved all disabled.
First, Funing District compressed air quality improvement increasingly smaller space, air pollution prevention and control situation is very serious, involving various enterprises must attach great importance to effectively assume responsibility for environmental protection.
Second, the coal-fired boiler in accordance with the "water power, chimney down, shifting the body" standard transformation and low nitrogen oxides emissions analyzer mounted nitrogen gas boiler work requirements, make sure the end of this completed, the embodiment late cut-off regulation.
Third, the Bureau of atmospheric sciences, environmental law enforcement unit to further strengthen law enforcement and inspection and supervision, the monitoring center to provide scientific data monitoring, to crack down on environmental violations, it is important to ensure that coal-fired, gas-fired boiler demolition, renovation work is completed on time.
Vertical steam boiler combustion characteristics combustion grate section with double action, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal. Gas steam boiler performance characteristics: 1, the furnace and comparing the old vertical boiler, heating area, rapid boost heating, less coal, high thermal efficiency, can save 25-30% of coal. 2, a furnace with multiple, user-friendly, the furnace can be used for the production of steam steaming canteens, disinfection tableware, bath heating, process steam, heating and the like locally heating the room. 3, the furnace with natural ventilation, induced draft fan and the blower does not need, no noise. 4, compact structure, installation, operation, easy maintenance, may be integrally handling, suitable flowability units. 5, heated with steam bath, food, heating, steaming, etc., pressure gauge scale strictly controlled within the design pressure, working pressure at any time shall not exceed the operating pressure. The scope of the steam boiler Application: can be used in textile, printing and dyeing, paper, food, rubber, plastics, chemicals, pharmaceuticals, iron and steel, metallurgy and other industrial products machining process required steam, and for enterprises, institutions, hotels, schools, restaurants, service industries such as heating, bath, air conditioning and hot water. Pledge: Since the equipment installation qualification pressure parts warranty 3 years, 12 months, auxiliary and lifetime maintenance, warranty period free of charge warranty for non-human failure (various defects caused by faulty equipment itself) of the Company, the replacement of damaged parts, the warranty period or man-made damage, is still responsible for maintenance and guidance equipment, for repair, replacement parts only fees. Quality assurance after the expiry responsible for maintenance of life.
Industrial boiler energy saving measures which industrial boiler energy saving measures which first of all, improve boiler regulations and standards. Speed up the boiler, boiler and pressure vessel manufacturing license conditions and modify Management for registration of technical supervision and management of energy-saving regulations, boilers, boiler design document recognition rules, regulations and technical specifications, energy saving and environmental protection index as a boiler manufacturing license, registration, design review compulsory requirements, strict implementation of energy-saving boiler design document review and styling products test system energy efficiency, energy saving, environmental protection, does not meet the safety requirements of the boiler, banning the production, sale and use, improve energy saving boiler threshold. Second, it increases energy-saving technology, new product development and promotion efforts. Key recommendations to improve the structure and level of technology stacks chain furnace exhaust combustion equipment, small boiler gasification combustion technology research and product development, coal-fired industrial boiler control technology research and product development. Development of gas condensing boilers, industrial boilers and energy-saving effect evaluation software audit, accounting boiler energy statistics and analysis system software research and development and other technical development work, through financial subsidies to accelerate the application of high efficiency energy saving boiler. Third, eliminate the old, inefficient boilers. Revision of coal-fired industrial boilers and energy-efficient economic operation, environmental protection and minimum limits of the system. The establishment of the old boilers, boiler inefficiencies out of the update mechanism, instead of a small boiler with a large boiler, instead of the low boiler parameters with high parameter boiler, instead of coal-fired boiler with a gas boiler or biomass boilers in the conditional area, thus greatly improving the energy efficiency. Safety of the boiler. The fourth is to strengthen the transformation of energy saving boiler. To improve the level of energy saving and environmental protection and industrial boilers fired boiler system, the automatic control system of the coal-fired industrial boilers, combustion optimization, heat recovery, frequency control, efficient desulfurization, denitrification and dust removal has been transformed, to improve the fuel water quality coal industrial boilers. Fifth, strengthen energy-saving knowledge management and boiler operators training. Boiler establish user management system, including energy-saving target assessment system, strengthen energy-saving boiler technical training of management personnel.
Cause of abnormal gas steam boiler stall phenomenon gas steam boiler and treatment of non-normal stalling reason, phenomena and treatment 2013-1-139: 17: 30 to cause a flameout: 1, or the operation of the auxiliary trip power outage. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, volatile or low calorific value gas. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
