filling bottle natural gas water pipe boiler dealer

Industrial production is inseparable from filling bottle water pipe boiler dealers, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.

According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.

The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.

New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.

Several problems into a coal-fired filling bottle water pipe boiler dealer fuel gas boiler fired boilers changed several issues should be noted that the fuel gas boiler: fuel oil (l) high temperature corrosion of the fuel used in the boiler, containing an organic salt of a metal element as sodium, vanadium class, after combustion of the low melting point eutectic oxide crystals, generally of about 600 ℃, or even lower. These oxides sublimation at a high temperature furnace, then condensed in a lower relative temperature of the heated surface to form a high temperature corrosive fouling. Is characterized by high temperature corrosion: the metal began to appear at temperatures in excess of 580-620 deg.] C, the higher the temperature, the faster the etching. High temperature corrosion measures to prevent: l) the use of additives. Mainly magnesium, calcium oxide, hydroxide or dolomite (CaC03, MgCO3) and the like, these additives can generate a high melting point compound with the component acting in a high temperature fouling, the fouling becomes loose and shape, so as to avoid or mitigate high temperature corrosion. 2) use high temperature materials with good corrosion resistance, high temperature corrosion resistant chromium steel is better than the nickel-chromium steel. 3) coated with a protective film. Susceptible to corrosion in high temperature heating surface ceramic surface coating, a silicon carbide or silicon nitride special coatings, the heated surface may be aluminized other treatment to improve its high temperature resistance. 3) coated with a protective film. Susceptible to corrosion in high temperature heating surface and other surface-coated ceramics, silicon carbide, silicon nitride, or special coatings, the heated surface may be aluminized other treatment to improve its high temperature performance rot cloud. (2) low temperature corrosion in fuel sulfur generated during the combustion S02, since the fouling atomic oxygen present in the furnace and the convection heating surface and catalytic oxide film, SO2 is further oxidized to S03. S03 and H2S04 vapor in flue gas generated in conjunction with, the dew point of the flue gas containing the sulfuric acid vapor is greatly increased, when heated wall temperature below the dew point of sulfuric acid vapor will condense on the walls, and corrosion of the metal wall. Usually low temperature corrosion It occurs at the end of the air preheater of the boiler. Thus when burning high sulfur fuel, care must be taken to prevent low temperature corrosion. Prevent low temperature corrosion measures are: 1) low oxygen combustion. When the excess air at the outlet of the furnace lag coefficient down to 1.10 or less, for sulfur of the fuel oil used, the dew point of the flue gas will be significantly decreased, so as to avoid or mitigate low temperature corrosion. 2) use of additives. Sprayed into the furnace or flue additive in the curb generation of SO3 and to reduce the flue gas dew point temperature. Common additives solid (dolomite, limestone, magnesium oxide, and some special compound), the liquid (aqueous magnesium chloride solution, some oil soluble magnesium, calcium, zinc naphthenate compound) and a gas (ammonia gas, ammonia, three different ring) three categories. 3) raising the thermal wall temperature, so that it is higher than the dew point temperature of flue gas. Commonly used methods are: hot air recirculation inlet temperature of the air preheater increase; the installation of the heater core, air is heated by steam, a low temperature air preheater horizontal structure, the level of a horizontal pipe line is arranged an air preheater , the air flow in the pipe, the pipe between the smoke flow, erosion due to the lateral wall of the flue gas, the flue gas side heat transfer coefficient is increased to increase the wall temperature, more generally vertical wall temperature of the air preheater increase 20 ~ 25 ℃. 4) corrosion-resistant materials or corrosion resistant coating materials include glass, ceramics and the like; an anti-corrosion coating and had tried to enamel-coated surfaces like special steel anticorrosion paint. 5) timely sootblowing operation, and therefore should be a reasonable arrangement sootblowers. Fire and explosion of fuel failure (3) heating surface of the tail or incomplete combustion of atomized droplets gather in the tail of the heating surface, when it reaches ignition or explosion conditions, i.e., ignition and explosion may occur. The tail heating surface fouling aggravated by the possibility of aggregation of the oil droplets. Therefore, when coal-fired boilers into oil-fired boiler, burner should be correct and rational selection and delivery, and strictly develop from the induced draft fan. Rules and procedures for shutdown and normal operation to ensure good fuel atomization, with the wind reasonable. At each of the heating surface is arranged to be reasonable sootblowers. (4) determining the dew point temperature of flue gas is determined dew-point temperature of the flue gas has practical significance for the design and operation of flue gas dew point temperature factors influence mainly sulfur fuel ink, excess air coefficient, water vapor in the flue the amount of sulfur / cement ratio and combustion.

Gas-fired steam filling bottle water pipe boiler dealer steam boiler gas to become the market trend is for countries to protect the environment, to control environmental deterioration and promote the steam boiler, gas steam boiler reconstruction is an arduous and urgent major project. Why the high price of coal to gas has changed, serious pollution of coal, especially in the past two years haze is particularly serious, mainly from coal to gas deal with environmental pollution, but the operating cost is much higher than gas. But the long-term development, economic development and should not expense of the environment, protecting the environment is everyone's responsibility. After gas steam boiler into a gas steam boilers, gas consumption is how much? Do not control coal, substantially in accordance with your boiler power to calculate, but one thing you need to think clearly, with the efficiency of gas-fired boiler efficiency gas boilers were quite different. So when you change 4 tons of coal boiler gas boiler, you can consider using a smaller gas-fired boiler. Coal to gas is a national policy not to install all right? Not installed, then it is possible, but now the country for gas-fired boilers is gradually ban, not to use, and if you do not choose coal to gas, then you need to select the coal to electricity, coal to heat pump etc., the gas must be slipping, these types of coal to the way you can compare each to see which is more suitable for their own gas steam boiler steam boiler gas into the benefits of what. Gas steam boiler includes a central water heater, new energy-saving, high efficiency stainless steel burner, electronic ignition pulse, a stainless steel coil heat exchanger, a strong discharge blower, intelligent control assembly elements, security devices and the like, the use of liquefied petroleum gas, natural gas, gas and other gaseous fuels, using the latest combustion technology design and manufacture of the heat exchanger, the thermal efficiency up to 95% water fast heating speed, high flow, with energy saving, easy to scale, automatic control without staff on duty, easy maintenance and so on. Economic and environmental performance far superior to the conventional type boiler modules may be stand-alone or in combination of line. Gas-fired steam boiler to save land resources, the same will not cause pollution like soot gas boiler. Gas boiler need to go through dust, slag process, complicated process, where the same water, gas boiler more environmentally friendly.
