Capacity Fire Tube Steam Industrial Gas Fired Boiler
Vertical steam capacity fire tube steam industrial fired 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.
Impact of vertical steam capacity fire tube steam industrial fired boiler efficiency is basically a bunch of the root causes of the country are carrying out high-profile coal to natural gas national movement, using the vertical steam boiler, very large cuts infected micro particles, toxic gases such as nitrogen oxides same time smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler. Combustion air is not sufficiently analyze the problem over the ratio: generally vertical steam boiler burner ejector, causing the air-fuel ratio can not maneuver scheduling. Lot of non-vertical steam boiler with automatic blower burner, leading to undesirable air-fuel ratio has the following several roots: air-fuel ratio does not contain points over about two cases: when oxygen is in excess, the excess cold air will have unlimited the effect of heat, resulting in increased operating costs vertical steam boiler, low vertical steam boiler efficiency; when oxygen is insufficient, will have insufficient incineration conditions, to produce low vertical steam boiler efficiency.
Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's capacity fire tube steam industrial fired boiler was planned.
Xuchang coal-fired boiler governance objectives:
In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.
Coal-fired boiler subsidy:
(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;
(2) the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;
(3) complete Chaigai coal-fired boilers for the end of October 2020, the prize money will not give up.
Xuchang boiler out of the way:
Removal, central heating alternative, coal gas, coal to electricity, use geothermal, wind, solar, biomass with a bag filter, to burn not including clean coal, coal-water slurry, anthracite, charcoal blue, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired capacity fire tube steam industrial fired boilers is much more serious than coal-fired boilers, for two main reasons:
1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.
2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.
