Cause of abnormal gas horizontal style 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.
In response to national environmental policy development, improve the quality of people's living environment of the area, Guangdong Province, actively promote the boiler "coal to gas" action. Currently, Dongguan City, "from coal to gas," the work has entered a crucial stage, nearly two months, the city government, city atmosphere Office, the Municipal Development and Reform Bureau has organized a thorough inspection teams to supervise the Towns "coal to gas" work . Atmospheric do inspection personnel Lurui Quan admits: "From the inspection situation, many companies on the 'coal to gas' is still in the wait and see attitude, worried about the safety and cost issues."
As of March 25, Dongguan City, 26 companies of 37 coal-fired boilers (except coal-fired captive power plant boilers), it has been out of the 17 units, 14 companies were using natural gas. In addition, 12 companies of 20 coal-fired boilers, is expected to complete phase transformation within this year.
It is expected that in the near future, all industrial boilers transform the use of clean energy, Dongguan sky will be bluer.
Operating cost comparison of different fuel horizontal style steam boiler below Henan fast boiler with small series to introduce the company's operating cost comparison of different fuel steam boiler. Refers to a steam boiler water heated to a certain temperature parameters, and the production of industrial steam boiler, water is heated into steam in the steam drum, the fire in the furnace emits heat, it is the principle of the steam boiler. Steam boiler belongs to special equipment. Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.2 yuan gas / side) fuel: steam boiler advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.5 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 0.6 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 900 yuan / ton).
Vertical horizontal style 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. Coal-fired 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.Free Chat
