hot water boiler pressure and capacity

What should be equipped with safety accessories boiler safety valve, explosion-proof doors, security seal, a low water level control alarms. Safety devices: a flow meter, pressure gauges, thermometers, fortune controller, water table and protection devices. Protection device: low water level alarm, low water interlock protection, vapor overpressure protection of the alarm and interlock devices, process control and ignition flameout protection devices. A safety valve the pressure in the boiler is controlled within the allowable range to ensure the safe operation of the boiler. When it exceeds a predetermined value, it can automatically open the exhaust steam, pressure relief, to prevent over-pressure boiler accident. Pressure gauge to measure the actual size of the boiler meter, pressure gauge value according fireman art, adjusting the lift of the boiler pressure, the boiler to ensure safety in the allowable working pressure. The role of water table is indicative of the high and low water level in the boiler, the water level in the boiler fireman help dynamic monitoring personnel to the boiler water level control in the normal magnitude of the boiler to prevent the occurrence of lack of water or full of water accidents. When the role of the vent is mild explosion in the furnace or the flue, can open their own relief, to avoid accidents and expand occur.

Gas waste heat recovery system process

ZG Boiler manufacturer in China since 1945, which is one of the world leading suppliers for process gas waste heat recovery systems (PGWHRS) and have been supplying high temperature and pressure waste heat recovery systems for more than 40 years.The group's vast experience and engineering know-how together with unique design features have been given a well earned distinction of being the world's leading and most proven and experienced manufacturers in process gas waste heat recovery boiler systems.

Steam boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

Gas boiler target pressure fluctuation of issues related to the target pressure is the vapor pressure of the gas boiler size needed to get the actual site. To pay attention to the following points: 1, the steam pressure is directly related to the quality of steam, steam pressure 1.0Mpa as a watershed, 1.0Mpa or less, the lower the vapor pressure, the worse the steam quality; 10Mpa above, the higher the vapor pressure, the worse the quality of steam . Meanwhile, the boiler load can directly affect the quality of steam: 2, at a vapor pressure of boiler water salinity and certain conditions, the boiler load increases, the amount of water vapor with a small amount tends to increase. If you overload the boiler is running, it will be a serious deterioration in the quality of steam. 3, the steam containing impurities damage caused by excessive heat, reduce the heat transfer capability, it will wall temperature exceeds the critical limit temperature to allow the metal, leading to over-temperature burn smoke tube. Steam ranging from the endothermic reduction, overheating temperature decreases, the exhaust gas temperature increases, reducing boiler efficiency. First, a common cause pressure fluctuations: 1 different manufacturing lines; 2 boilers used in combination can cause pressure adjustment... II Solution: modified if necessary according to the actual pressure, it should be carried out within a small range stepwise correction, e.g. 0.02 adjusted up or down. Third, the professional advice: It is recommended to run at a higher pressure, increasing the pressure relief valve at the end. High-voltage transmission principle, the use of low pressure. 1, the advantages of the high pressure steam conduit delivering steam A. The small-diameter, heat loss;. B steam pipe lower costs, support costs less, low labor cost;. C lower cost insulation pipe;. D reduced pressure by using point may be obtained drier steam;. E high pressure boiler is easier to achieve optimum operation, higher operating efficiency;. F increase the heat storage capacity of the boiler, is easy to handle changes in load, and to reduce the priming with water possibility. 2, the low pressure steam pressure reduction A. advantages may be provided in a greater proportion of the steam latent heat;. B reducing the pressure of condensed water can be reduced calories, reduced secondary steam;. C under reduced pressure vapor after having a higher dry degree.
