After normal hospital steam atmospheric boiler manufacturer outage, why should the use of natural buck? Since the saturated water vapor having a certain temperature under a certain pressure, when the pressure change, the saturated water and saturated steam temperature change accordingly. If the boiler shutdown pressure drops too fast, the saturated water and saturated steam temperature dropped significantly. Due to the high rate of change of pressure saturation temperature at a lower pressure, because the saturated vapor in contact with the drum wall, the lower wall in contact with saturated water vapor than the thermal conductivity of water is large, the heat accumulator drum lower wall water to pass quickly the drum wall at a temperature close to the saturation temperature at the new pressure after the pressure drop, and poor heat transfer walls of the drum to maintain a higher temperature, the drum wall temperature is higher than the wall temperature, the faster the vapor pressure drop, the drum, the greater the temperature difference between the lower wall. Simultaneously vapor pressure decreased too fast, which also decreases the saturation temperature corresponding to accelerate the wall temperature waterwall, economizer header and the faster decline, due to the rapid cooling, the contraction will have a great thermal stress, local joint, at the weld easy to crack, so the boiler outage to take normal blood pressure naturally. When the normal flame boiler shutdown, soft drinks all doors should be closed, closing dampers, Manhole the boiler is in the closed state, allowed to cool down.
Henan gas hospital steam atmospheric boiler manufacturer by techniques which optimize the effect of reduction of Henan gas boiler, i.e. the part of each combustion system design, heat exchanger components and control system can improve the boiler efficiency optimization techniques combined together, will be the maximum It may improve the thermal efficiency of the boiler, so as to achieve energy saving. 1. Using burner head premix metal fibers. First, natural gas and air through the venturi tube to achieve optimum mixing, the mixed gas is combusted in the combustion surface of the first woven fibers made of special alloy, burning more fully, more thorough, flame generation is extremely short, so the required combustion small room space, so a premix burner Henan gas boiler more compact. Secondly, when the premix type burner flame color is blue, the flame temperature of about 1000-1100 degrees, ordinary blower burner flame temperature greater than 1300 degrees, and the oxygen and nitrogen in the air from the start of the reaction is about 1200 deg.] C, A vigorous enhanced from 1500 ℃. Therefore, NOx emissions is much lower than condensing furnace blast other common boiler burner. Further noise premix burner produces approximately 40-72dBA, the blower noise generated by the burner is high 80-100dBA. A flexible metal fibers also avoid the generation of thermal stress of combustion head, extending the service life and maintenance intervals burner head. 2. Henan new gas-fired boiler using heat transfer enhancement of heat transfer tubes. In order to reduce exhaust gas temperature, the condensing effect is achieved, increasing the heat transfer area of the heat exchanger must element, it should not be construed to simply increase the volume of the device to increase the heat transfer area. But should be reasonably increase the heat transfer area per unit area of the device, and high thermal conductivity, and is corrosion resistant heat transfer tubes. 3. flood capacity design makes operation more sustainable, start and stop times smaller. Significantly reduced consumption and emissions. 4. Application of PVC exhaust pipe. Since conventional boiler flue gas temperature above 150 degrees, the chimney must be made of steel, but also the use of prefabricated chimney insulation layer stainless steel in some cases, the cost per square meter of the chimney 1600-1800 dollars, the cost is very expensive. Henan gas boiler due to lower exhaust gas temperature, standard PVC pipe may be used as exhaust pipe, the boiler is greatly reduced additional installation costs. 5. Henan gas boiler provided with the water receiving tray collected condensate, and the condensate and treatment before discharge. During condensation of gases and fly ash and soot fraction of the flue gas is dissolved in water, reducing the harmful substances discharged into the atmosphere. 6. The controller comes selection ratio control system and having a sound and timing of the operation mode. Fast and accurate continuous tracking load changes, to achieve good time-heating function.
Henan hospital steam atmospheric boiler manufacturer maintenance in a safe manner What? Our Henan boilers generally are water or organic carriers for the media, Henan detected under high pressure boiler is particularly important, its operation is relatively complex internal structure and its corresponding inspection workload is huge, coupled with the complexity of the scene , the requirements for testing the quality and intensity of high, following Xiao Bian will analyze the way for everyone Henan boiler maintenance industry-leading security which. 1, implement preventive measures boiler safety inspection in Henan boiler as a special device, unlike washing machines, color TV sets and other household appliances, in the factory, installation, maintenance, alteration, use before acceptance, qualification aspects of the operating personnel have done a corresponding legal approval provisions. When trusted Henan factory boiler, the boiler must be accompanied by drawings, strength calculations of pressure parts, safety valve emissions calculations, the quality certificate of boilers, boiler installation manuals, operating instructions and pressure parts design change notices, etc. relevant technical information. For non-technical information product quality supervision and inspection certificate, it must be made by the local labor department or its authorized Inspection issued. 2, routine maintenance investigation danger First, it should be professional and meticulous examination of all enterprises in Henan boiler, to determine which of these can have the installation qualification. Second, prior to installation of each boiler are all related work for the record, no one appears to prevent accidental accountability situation. Third, the need to continue to observe the working conditions and the water pressure is stable within a certain time after the installation is complete, again to determine whether the successful completion of the installation work. If abnormal situation occurs, consumers need to require the installation of the unit to be first at the scene, hidden dangers and rigorous investigation of work-related deal with the aftermath, to ensure safe use of the boiler. 3, pay attention to the special nature of the operator qualification Henan boiler, it is necessary for the installation of the use of qualified personnel in certain countries allowed to carry out checks for this category is related to the people and social security facilities, the state has adopted in this regard test methods and professional qualifications of audit and examination are very strict. National quality control personnel this one, it must have a professional qualification in a boiler factory in Henan to participate. In the case of determining the relevant parameters, technical requirements without any problems allowed to produce and sell. In everyday use, but also mindful of the problems related to the regularity or direction, to pave the way for the smooth conduct inspections in the future. In short, the boiler because of its special structure and use, and for the people its security is critical, remember to consumer safety and proper use of the boiler, as an ordinary user, pay attention to the proper use and daily periodically check that the relevant part of the part to be able to ensure normal Henan boiler presents the best results.
