WNS is a wet potshell three horizontal fire tube fired condensing boiler return, this structure has three returns, the oil or gas well atomizer air mixed with the combustor, the combustion in the furnace corrugations, into the first chamber after smoke return pipe, a second front steering return pipe smoke box, smoke box after the last to, through the chimney. It different fuel has a strong adaptability, it can burn heavy oil, light oil, natural gas and city gas. Boiler type low cost, high efficiency, security and stability, space-saving, fuel-efficient, low-cost investment to buy fuel; all pull side butt welds, boiler safety, long life, low maintenance costs. Recovery tail with flue gas condensation, can effectively control the flue gas temperature, high thermal efficiency of the boiler. Quick installation structure, the overall performance of the boiler on the basis of high strength steel design, easy installation and transportation, saving space in the boiler room area.
Boiler installation of "blast doors," What is the role now on the market most of the fired condensing boilers 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.
The output power of the burner should be matched with the rated output of the fired condensing boiler, and the shape of the flame, such as length and diameter, should be selected to suit the furnace structure. Supply the air needed for fuel combustion from the torch root to make the oil mist or gas and air mix evenly and quickly to ensure complete combustion.
Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast fired condensing boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .Free Chat
