high efficiency gas fired steam boiler
Gas-fired high efficiency fired steam boiler steam boiler and gas accounted for half of the market at any time, more and more national attention to environmental protection, gas steam boiler has been hit hard. In contrast, gas steam boiler by many users of all ages. In recent years, also vigorously promote the use of gas-fired boiler. Gas-fired steam boilers What are the benefits? Let us discuss with you today. Gas-fired steam boiler steam boiler and gas market accounted for half of the market, showing a trend of resistance of court, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: Obviously, in terms of technical gas boiler and auxiliary aids far ahead of the gas boiler, and is equipped with a special gas burner. 1 ton steam boiler, for example, gas boiler about 30% higher than the gas boiler. 2. Construction cost: This cost mainly from the boiler room. As more gas steam boiler auxiliary equipment, boiler house construction should invest more money. Less gas boiler auxiliary equipment, automatic control operation, with automatic alarm and automatic protection, saving the cost of housing, safe and reliable. After natural gas pipeline, the burner will automatically supply, cost-effective employee. Gas boilers also need to pay some wages, because they need to participate in coal plan. 3. fuel costs: You can clearly see this by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. environmental costs: In the need to protect the environment, the review of the gas boiler are becoming increasingly stringent. Because of the economy, environmental protection and energy as well as government policies, gas steam boilers more and more widely used.
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.
Winery method which reduce pollution 1, check for leakage protection and maintenance of: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, repeated use of steam condensate: S. Mills requires a lot of saturated steam in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, the piping, valves and heat insulated flange experience pipes, valves and flanges waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery from the boiler chimney at a temperature of 360 ℃ smoking, sometimes discharged directly into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of the winemaking equipment Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
The Hulun Buir City, Inner Mongolia, due to its special geographical location, well into the cold season, heating boilers put into use. Safe use of district heating boiler equipment, Hulunbeir special inspection carried out the inspection work to ensure the operation of heating boilers for the Evenki Autonomous Banner Dayan Town, tie Nihe mine, Bayan hematoxylin lofty Kong and other regions.
Inspectors checked one by one aspect of the boiler, safety accessories, ancillary equipment, water quality management and data review and so on; and the verification process in all corporate communications using the boiler should pay attention to regulatory knowledge and safety knowledge, urged business executives to issue timely corrective to ensure the safe use of heating boilers.
