water fire tube coal fired hot water boiler
Cooperation with the fast boiler really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
Works chemical plant boilers is what works what chemical plant boiler is? Energy conversion device is a boiler, a boiler input energy comprises a chemical energy, electrical energy, thermal energy of the flue gas temperature and the like. After conversion of the boiler, steam, water or high-temperature organic heat carrier having a certain thermal energy to the boiler outlet. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main principle is a use of the chemical energy released by combustion of boiler fuel or industrial waste heat transferred to the water container, the water reaches the desired temperature or pressure of the steam heating apparatus. Boilers and boiler furnace two parts at the same time, water enters the boiler, the boiler heating surface in the steam - water system will absorb heat transferred to the water, so that by the hot water reaches a certain temperature and pressure to produce hot water or steam or, is introduced into the application. cation. In the combustion apparatus part, sustained release heat of fuel combustion, high temperature flue gas produced by combustion heat propagation, to transfer heat to the boiler heating surface, the temperature itself is gradually reduced and finally discharged through a chimney. Works chemical plant boilers is what - Classification steam boiler: First, the fuel can be divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4 electric boiler, boiler and nuclear 5, 6, waste heat boiler, etc., most top four, the most common, the lowest operating costs of coal-fired boilers, but a large area, serious environmental pollution, the requirements of operators, gas boilers high degree of automation, operating costs than coal, accounting small land area, requiring fewer operators, I did not use electric boiler, but running costs should be the highest, but the small boiler footprint, environmental protection is the best, the other boiler is not introduced, because I do not understand you the meaning of. two. The heat transfer mode can be divided into water-tube boilers, the thermocouple tube boiler, water tube boilers and fire tube boiler. Usually gas fuel boiler fire tube boiler, typical Type: series WNS (horizontal combustion boiler combustion chamber), this boiler characteristics: simple structure, the rated capacity of the evaporator is generally small (typically 10 tons or less, have a greater , but generally not more than 35 tonnes), starting the furnace pressure faster, lower quality requirements boiler; coal-fired boilers typically water boiler. Tube boiler, water tube boiler high thermal efficiency, but the complex structure of the boiler a higher quality requirements.
SZS structure which forms the water tube boiler described below common small water tube boiler: the boiler is mainly composed of vertical boiler tubes, water wall header, the downcomer, the convection tubes and other components (FIG. 3-12). It evaporation capacity is divided into 2t / h and 4t / h, which is the simplest structure water-tube boiler and a minimum capacity. In the furnace chamber, two horizontal drum of the drum water is not a vertical line in the center, minor drum forward, tubes convection expansion joint between two rollers. Seamless steel tube is curved convection bank of 51 mm formed by the outer diameter. It is arranged in a row, is provided a smoke screen between the tube wall folded, Z-shape so that smoke passes through the tube bundle. Wall and ceiling are arranged in the furnace front wall. Wall arrangement bow front lower portion of the side wall. Extracting two downcomer barrel from both ends of the boiler, through the lower wall of the header connector with the side walls of the water wall. Elbow boiler waterwall tubes and convection, readily expandable, unitary structure having a good elasticity, a large volume of the furnace, for burning various fuels. However, the use of coal workers' labor intensive; less heating surface arranged furnace surface, not the tail flue economizer, the exhaust gas temperature is high, the low efficiency; convection tubes easy to fouling. Two Longitudinal bend tube boiler drum (D-type boiler) D-type arrangement is very common in recent years, a small boiler tube arrangement, which is characterized essentially in the same vertical twin drum center line, parallel to the chamber axis double drum shaft furnace, boiler and the side of the water wall, the other side of the flues and convection heating surface tubes, D type boiler. D-type arrangement are also used in oil-fired boilers. Figure 3-13 shows a D-type boiler having a vibrating grate. Drum main ingredient is water, convection bank, Wall System, (water wall, the first downcomer), economizer , such as some boiler superheater. Slightly larger than the diameter of the cylinder barrel diameter of convection bank connected between two reels. Convection tubes of 51 mm outer diameter of a seamless steel composition, disposed in the convection pass convection pass, convection pass longitudinally along the refractory wall into two half-regions, the flue gas convection pass along a U-shaped flow. Fireplace decorative walls, all around the side walls and the downcomer is provided with fixed frame, form a closed water circulation system.
Industrial boiler energy saving measures which industrial boiler energy saving measures what? First, 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.
