combined gas fired condensing hot water boiler dealer

First, the design principle WNS type boiler and a gas main features. 1, WNS type boiler design principle and structure: WNS is a wet back boiler shell three-pass horizontal fire tube boiler, this structure uses three return, the oil mixed with air or gas well through the atomizing burner, in the complete combustion furnace in a corrugated, folded from the rear chamber into the first tobacco smoke return tube, to a second smoke box to the front return pipe tobacco, tobacco after entering the last tank, is discharged from the chimney. It has strong adaptability to different fuels, combustion of heavy oil, light oil, natural gas, city gas. Low power consumption, load regulation ratio. Boiler automatic control, adaptability of the burner. Using imported burner, reliable performance, high degree of automation. 2, the main features of the WNS type boiler: High (1) combustion efficiency, safe and stable, space-saving, fuel-saving, low investment costs to buy fuel; (2) full-pull edge butt welds, boiler safety, long life, maintenance costs low. (3) there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; (4) with automatic burner, water continuous electric adjustment, high combustion efficiency. (5) The quick configuration, the entire boiler design on the steel strong base, easy installation and transportation, saving the boiler room floor space area. Two, SZS type gas boiler structure and characteristics: SZS longitudinal type double drum "D" type arrangement quick water boiler. It consists of upper and lower drum, membrane wall, the convection tubes, condensers, and economizer, disposed in the front wall of the burner, the combustion of the fuel in the furnace, flue gas convection bank, an economizer and a condenser into the chimney. The main features are: (1) The double boiler drum "D" type arrangement, compact, small footprint, good flame fullness. (2) the boiler supporting mode can be free to expand upwards. (3) furnace wall and membrane in all convection pass wall structure, good sealing and maintenance work and reduce the use of refractory bricks. (4) The quick boiler structure can effectively shorten the installation cycle. (5) arranged economizer tail, can effectively reduce the exhaust gas temperature, high thermal efficiency of the boiler. (6) The whole boiler steel seat strong base, easy transportation and installation. (7) having a heating surface surplus, soda and a sufficiently large space to ensure stable boiler parameters. (8) with automatic burner, combustion efficiency and an ignition control program and overpressure, flame protection. Third, the application type WNS and SZS boiler used in Example 15 t: In addition to evaporation, working pressure, as the fuel is used, the two contrast, WNS size slightly smaller type gas boiler, small footprint, from a cost perspective, slightly lower than SZS type gas boiler, the thermal efficiency of the boiler is almost the same, but their difference only lies between 1 t -20 t tonnage, the conventional WNS type gas boiler, and SZS-type gas-fired boiler more than 4 tons -60 tons, even to 90 tons.

10 tph WNS series gas-fired steam boiler renovation project for Urumqi Railway

ZOZEN has played an active role in promoting the process of "coal to gas". In particular, the WNS series of gas-fired steam boilers have gained a good reputation in the industry due to their safe and efficient performance. This gas-fired boiler features compact design and is equipped with boiler control, alarm and interlocking devices of water level and steam pressure to ensure safe and reliable boiler operation. And the large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes increase the heating surface. With the energy-saving device at the tail of the flue, the exhaust gas temperature is reduced below 60℃, and the thermal efficiency is as high as 98%, helping clients achieve their goal of energy saving and emission reduction.

Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.

Henan Flower cattle group under the Animal Husbandry Bureau of Henan Province, is set cow breeding, seed promotion, dairy processing, food processing, veterinary preparations and the manufacture of APIs for an integrated group of companies. Dairy Engineering Technology Research Center, Zhengzhou City, Henan Province, as well as dairy Engineering Research Center, Biological Engineering Research Center of veterinary drugs, dairy cattle breeding Engineering Technology Research Center and other representatives of the region, the industry's highest level of scientific research institutions are located in Flower cattle Group.
