Gas industry steam fire tube boiler dealer which has few parts of the main gas boiler: the enclosed pipe chimney pipe tube sheet base gas outlet steam dryer Confining the majority of the peripheral tubes to form a complete gas boiler. The main effect of gas boiler: the combustion of the fuel is heated by the feedwater temperature and the exothermic heat of the flue gas with a heated surface, so that a final water into superheated steam having a quality of qualified certain parameters. The water in the boiler to go through preheating, evaporation, overheating in three stages in order to become superheated steam. In fact, in order to improve the efficiency of the steam power cycle, there is a fourth stage, i.e. re-superheating stage, soon after the high pressure turbine expansion work to reduce the pressure and temperature of the steam back to the boiler is heated and then sent to the low pressure turbine cylinder continues to work. In order to meet these four phases change, the boiler must be arranged in the respective heating surface, i.e. the economizer, water wall, superheater and reheater. Superheater and reheater disposed in an upper horizontal flue backpass and functions of the fuel system is to ensure the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. Economizer disposed in the lower back pass. In order to utilize flue gas heat of heated air required for combustion, usually air preheater arranged after the economizer. Some additional preheating large boiler superheater heating surface or in the furnace, and then heat-receiving surface.

The working principle of steam industry steam fire tube boiler dealer steam boiler with boiling water almost equivalent to pot kettle, oven stove equivalent. Boilers and boiler furnaces is divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam. Popular terms, the steam boiler is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. For example, everyone knows to pulverized coal, for example. 1. The operation principle (an example in pulverized coal fired boilers) in heat pulverized coal combustion furnace, radiative heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for steam separator (DC furnace excluded), the separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2. Pulverized work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small; also affects the position of the center of the flame superheated steam or reheat steam temperature, generally lower the center of the flame in particular superheated steam reheat steam temperature to be low, otherwise higher. 3. The arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion.

Scale thermal conductivity gas steam industry steam fire tube boiler dealer is only one out of steel gas steam boiler efficient and environmentally friendly use of non-corrosive cleaning agent in the cleaning process of cleaning the boiler. This will cause the device to the metal tube is exposed to the primary colors, and reduce the effects of biological fouling algae sludge. After ignition gas steam boiler, furnace and to observe the temperature of main steam. Main steam pressure rises, the boiler flue gas temperature significantly higher ignition. If the temperature does not rise, you should immediately to the scene to check the oil gun fire. Scale thermal conductivity gas steam boiler is only one-tenth of steel. When it is scale on the heated surface, which will hinder the heat transfer effect. To maintain the boiler output constant during use, the need to increase the temperature of the combustion side. Gas-fired steam boiler furnace exit temperature rise, increasing the loss of gas steam boiler scale on the device can effectively reduce the water wall heat transfer, the temperature of the water is likely to lead to an increase in the wall, resulting in a wall of water burst. When the gas steam boiler, the furnace will be a series of chemical and physical reactions. During use, it will be effective to form a dense and hard scale on the heating surface, which will lead directly to heat exchange. Due to the scale and efficiency while reducing corrosion can lead to heat gas boiler absorption.

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.
