2800kw low pressure coal fired hot water boiler
Gas boiler market prospects of geometry: divided by fuel coal, fuel (gas), electric steam furnace. Fuel oil (heavy oil and light oil is divided) gas (divided city gas and natural gas) 2800kw low pressure coal fired hot water boilers that burn oil or gas fired boilers can heat the water. Development of sub-pot boiler and furnace two aspects.
How to improve the energy efficiency of industrial boilers 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.
Features boilers are widely used in petroleum, chemical, pharmaceutical, textile, light industry, building materials and so on. A low pressure, high temperature, safe, energy efficient features. Operating with complete control and monitoring of safety devices, the operating temperature can be precisely controlled. Reasonable structure, fully furnished, short installation period, easy operation and maintenance, ease of boiler arrangement. Since electric heating furnace Heat Transfer Fluid advanced explosion-proof structure, it can be used in factory area Ⅱ proof, explosion-proof grade C up to level. In recent years, due to the need for environmental protection and rising oil prices, many local governments and enterprises will be coal-water slurry fuel as a clean alternative to oil to be used. Especially in the small and medium industrial boilers. CWS boiler market development trend, there are two, one is modified in accordance with the way oil furnace coal boiler, namely the design (CWS oil boiler) on the basis of oil furnace system; one is in accordance with the bulk coal transformation of the way CWS boiler furnace, namely design (bulk coal water slurry boiler) scattered coal stove in the system. Before the existing oil-fired boilers plus pre-furnace. Advantages: high degree of automation, small volume, pleasing in appearance; disadvantages: complicated equipment, pre-furnace combustion pressure, high temperature, easy to ash fusion, pre-furnace coke, slag is very difficult, not suitable for continuous operation. The principle is the bulk coal boiler design, little change furnace, auxiliary substantially constant configuration parameters, the first half of the boiler combustion good, but the rear of the flue gas emission unreasonable, because different from the coal for coal-water slurry, coal slurry containing 34% to 38% moisture, so the contained amount of water vapor in the flue gas, so that dust desulfurizer two tails, induced draft fan and stack gray water condensation, clogging and corrosion. Excessive speed plus smoke, fine dust, very large friction, serious damage to the auxiliary equipment, continuous operation can not lead to a discharge portion, the discharge of non-compliance.
Beiqi Panther car 6 tons of steam condensing one fuel gas steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
