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).
According to fuel (electricity, oil, gas), oil-fired gas boiler can be divided into three kinds: electric steam boiler, oil-fired steam boiler and gas-fired steam boiler. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small and medium-sized steam boilers are mostly single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. The following is the boiler pressure fire shutdown time more than 6 hours, the boiler main steam valve should be closed after a period of pressing fire, opening the superheater outlet header drain valve, to cool the superheater. If the air pressure rises after the main steam valve is closed, it can be used to lower the pressure of the boiler by feeding the water into the boiler and simultaneously discharging the water. Press. When the boiler resumes operation, it needs to go through the pressure rise and protect step 2. There is still steam pressure in the pot during the shutdown period of the pressure fire, so it is still necessary to pay attention to monitoring and make the boiler keep the allowable water level 3, the boiler with cast iron gas saving gas, after the boiler stops feed water, The gas-saving flue baffle shall be closed, the side-hearth baffle opened or used in the circulating pipeline to stop the water temperature in the gas-saving area exceeding the specified value of 4, the proper discharge shall be carried out during the shut-down of the furnace under pressure fire, and the sediment in the furnace shall be excluded. The operation of circulating water pump should not be stopped immediately after the furnace shut down. The circulating water of network should be kept circulating in the system for a period of time, and the water temperature of boiler outlet should be lowered below 50oC. The operation of circulating water pump can not be stopped until the operation of circulating pump is stopped.
The most common utilization of solid fuel biomass is direct combustion with the resulting hot flue gases producing steam in a boiler—a technology that goes back to the 19th century. Boilers coal fired burn a variety of fuels and continue to play a major role in industrial process heating, commercial and institutional heating, and electricity generation. Industrial boilers are differentiated by their configuration, size, and the quality of the steam or hot water produced. Power plant boiler size is most often measured by the fuel input in MMBtu per hour (MMBtu/hr), but it may also be measured by output in pounds of steam per hour. Because large industrial boilers are often used to generate electricity, it can also be useful to relate boiler size to power output in electric generating applications. Using typical coal fired boiler and steam turbine generating efficiencies, 100 MMBtu/hr heat input provides about 10 MW electric output.
Gas-fired boiler, fuel gas-fired boiler, fuel gas hot water boiler, steam boiler fuel: gas boiler includes a gas water boiler, gas hot water boiler, gas steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, gas as the name suggests refers to the boiler fuel for the gas boilers, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. Gas boiler comprising KS-Q water gas boiler, CLHS (CWNS) gas hot water boiler, LHS (WNS) gas steam boiler and the like, wherein the gas comprises a gas hot water boiler heating boilers and gas boilers bath, with the state "natural gas "project implementation, gas boiler gradually become the people's choice.
