Most competitive best condensing gas 4 ton natural steam boilers
Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.
By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.
After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.
In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.
"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.
Basics gas and steam oven basic principle as the principle gas most competitive best condensing 4 ton natural steam boilers and knowledge: steam as a heat carrier gas, forced circulation pump circulating the liquid phase, and then reheated to return, once-special industrial furnace. Widely used, such as petrochemicals, textiles, printing, plastics, rubber, food processing, wood processing, thermal asphalt, carton production, vegetable dehydration, drying, and other drying foundry sand. Gas steam boiler is an energy, security, heating equipment, is an ideal alternative to steam boiler products. The working principle is conveyed back to the respective thermal heating apparatus petroleum oil heater (endothermic) (organic heat), heat conduction through the (thermal energy release), and then returned to the furnace, formation of a closed circle in the process of compulsory to achieve the purpose of heating. Performance and features: 1, low temperature. As the temperature rises conductive oil, the viscosity of the system will continue to reduce resistance to decline, it will also reduce stress, more conducive to the safe operation and safe operation. Steam boiler is high pressure high temperature plume. 2, gas and steam heating system uses hot water inlet and outlet temperatures and equipment is 20-30 degrees, the closed forced circulation, heat recovery can be repeated, there is no waste, high thermal efficiency, energy-saving effect. 3, a low pressure gas and steam heating system, requires pressure equipment and the system will be reduced, and therefore, a simple production process of steam boilers, low investment costs. 4, the thermal efficiency can be maintained at optimal levels in various loads a level of 320 degrees and can adapt to the production requirements of the following types of thermal load, and temperature control can be precisely adjusted. 5, heating furnace to increase two to three times the temperature cycle can provide a wide range of processes, a variety of equipment to meet the different temperatures greatly reduces the need for investment in equipment.
Combustion characteristics and operation of most competitive best condensing 4 ton natural steam boilers steam for steam boilers everyone know how much will the following to let everyone have a preliminary understanding of the steam boiler by two aspects, but also hope to give a friend wanted to buy a steam boiler of some help. Chain-type layer is generally fixed combustible fuel steam boiler chain grate or a grate (the traveling), it is fixed only for small coal-fired boilers. The most commonly used medium-sized coal-fired boilers or for chain grate, as the chain travels will gradually sent to the tail of the coal grate in the process of moving complete fuel combustion tube from the inlet to the lower part of the grate grate internal supplemental air required for combustion, ignition top-down, no ventilation grate uneven seam and around the relative movement, through non-flammable. After heating area of the heating flue gas temperature of the working fluid designed to flow through the same furnace hot flue gas and heating surface arranged in the other exhaust flue boiler. Incidental chain grate type, scale type, beams, and other means, the current domestic applications mainly for small and medium-sized joint type and scale type chain grate, generally large chain grate beam type. Former steam boiler steam boiler system to start all waterproof steam cylinder valve open, let go condensate. The inlet steam valve slightly open, to warm up the cylinder, drain cocks to be out after closing the steam, drain cocks. The steam valve was then opened progressively larger until drainage tank vent cock and water out there, and closed vent cock drain cocks. Turn on the water supply valve to the boiler feed water. Steam boiler in operation if there is gas in timely attention tank, water tank periodically open the air discharge valve, in order to avoid air resistance tank, the influent. Pump flow regulator bypass should be adjusted to achieve the degree of opening of the valve, and not with a method of adjusting the outlet valve is adjusted. At the rated discharge pressure of the pump, which inlet pressure should not exceed a predetermined value. Inlet and exhaust pressure difference should be maintained within a predetermined range. Steam boiler steam valve should be shut down first, then turn off the water valve and turn on the water valve is open, then turn on the water faucet open the lower part of the tank and cylinder, the cylinder water drain. Of steam cylinder reciprocating pump, which cylinder two stroke difference should not exceed 5% of rated travel.
（9）Combustion Adjustment method of Oil-fired Gas-fired Boiler
The combustion adjustment of oil-fired gas-fired boiler is successful and the load adjustment can be carried out after turning into normal operation. At this time, the combustion situation in the furnace should be observed frequently. If the atomization of oil and gas is not good, the flame jumps, the flame hits the furnace tank, and the exhaust temperature is too high or too low, the oil pressure, oil temperature, steam volume, air pressure and steam pressure should be adjusted in time to ensure the safe and economical operation of the boiler. The oil pressure and the pressure are related to the boiler load. The adjustment of the oil pressure is realized by adjusting the pressure of the burner or the amount of oil returned. The adjustment of air pressure is achieved through the opening of the valve. When adjusting a load, enter At the same time, the air volume adjustment must be carried out synchronously to ensure the reasonable match between the oil quantity and the air volume, so as to achieve the purpose of economical operation of the boiler.
