15 ton powerhouse temporary gas boiler systems for sale
Boiler installation of "blast doors," What is the role now on the market most of the 15 ton powerhouse temporary boiler systems for sales to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.
"Coal to gas" birth 15 ton powerhouse temporary boiler systems for sale gas demand "from coal to gas" is one of the primary means to reduce air pollutant emissions. China's industrial coal-fired boilers, mostly without washing of coal, higher emission levels, the contribution of urban air pollution by up to 45% -65%. "Coal gas" will be replaced by coal-fired boiler, gas-fired, can significantly reduce emissions. In 2012, a number of ministries such as Ministry of Environmental Protection issued a document repeatedly requested the transformation of emissions large boiler products, such as "air pollution control in key areas" Twelfth Five-Year Plan "key projects" in the requirements, completed 2015 2841 clean energy transformation station over coal-fired boilers, which made it clear 465 coal-fired boilers replaced by a natural gas boiler. Since 2012, Beijing, Shanghai, Shijiazhuang, Lanzhou, and other places have been put forward more detailed policy requiring replace coal-fired boilers to natural gas boilers. Research shows that "coal to gas," the economy is weak, the policy is the main driving force. Due to higher gas prices, "to burn" after higher operating costs, such as coal-fired boiler and a full set of environmental protection equipment total annual cost of 661,900 yuan / (t / h), "coal to gas," the total cost of the annual 844,300 yuan / (t / h). Although a single coal-fired boilers to burn the economy is not strong, but mostly coal-fired boilers into a large gas-fired boiler feasible. Policy is the main driving force to promote the "coal to gas." It is understood that the gas boiler is facing 80 billion market demand, industrial boilers for the heavy head. According to "energy development" five "plan", "Boiler Air Pollutants Emission Standards", estimates derived gas boiler market space "Twelfth Five-Year" period about 800 million yuan, of which the industrial gas boilers for the heavy head, the market is 60 billion yuan; large gas power plant waste heat boiler to invest 150-180 billion yuan, natural gas distributed generation waste heat boiler to invest 50-60 billion yuan. According to "Natural gas development," second five "plan", 2015, China's natural gas supply of about 269.5 billion cubic meters. The demand side, China's gas power plant in 2015, distributed projects, industrial boilers totaling nearly 100 billion cubic meters of natural gas. By then sufficient air supply without worrying about gas shortage.
It provides fast side of 15 ton powerhouse temporary boiler systems for sale equipment, installation and commissioning after all normal, we immediately put into use, the hotel did not delay the normal heating. Meanwhile boiler capacity, energy efficient, fully able to meet the needs of heating and bathing water in our hotel rooms. --customer feedback
In the two oil crises of the 1970s, natural gas was used as a fuel for 15 ton powerhouse temporary boiler systems for sales.
By the early 1990s, fuel-fired industrial boilers with a certain degree of technological development had a high market share in the boiler market.
