energy saving natural gas fired steam boiler for industry
75 ton CFB boiler
Fuel Flexibility: The most important advantage of the CFB boiler is the flexibility of firing a wide range of coal from 9500 to 25000 kJ/kg. CFBs can also burn a limitless number of other types of solid fuels, separately or mixed with coal. The limitations if any are only in the feeding and other mechanical equipment. The output capacity and steam parameters depend on the heating value of the fuel.
75 ton CFB boiler can use different types of solid fuels that include low quality coal, lignites, coal blends, bagasse in sugar plants, bark in pulp and paper mills, coal washery rejects in mines, petcoke and other bio mass products. Most of these fuels are seasonal, production or availability dependent. Mixing with coal or using coal when other fuels are not available gives an uninterrupted steam and energy supply.
1. Sulphur Dioxide removal: Firing high Sulphur coal requires the use of a Flue Gas Desulphurisation (FGD) plant to keep emissions within statutory limits. An FGD is a complicated plant that requires high capital investment and operational cost. In a CFB limestone addition in the furnace converts the SO2 to sulphates during the combustion and circulation which goes out with the ash. A CFB boiler costs less than a PC fired boiler with an FGD.
2. NOx Reduction: The combustion temperature in the furnace in a CFB boiler is considerably less than PC boilers resulting in lower NOx emissions. There is no additional requirement of separate NOx capturing devices which reduces capital investment.
3. Maintenance: Eliminating the pulverizer and pulverized coal piping reduces maintenance, related outages and equipment redundancy. A part of this saving is offset by higher maintenance due to erosion in pressure parts and furnace area, and maintenance of the refractory.
Gas energy saving fired steam boiler for industry and the hydraulic classification precision classification by use gas steam boiler 1, an industrial gas steam boiler: heating and the like used in industrial production. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.
Safety rules energy saving fired steam boiler for industry steam boiler production, life indispensable important equipment. Boiler room is a vital part of my unit. Steam boiler having a high temperature, high pressure characteristics in use. Such as poor management, will be an accident, causing casualties, the production interruption caused serious losses to the school and state. So each time fireman and maintenance personnel to maintain a high degree of responsibility in their work to ensure the normal operation of the boiler, strictly adhered to. A strict compliance system fireman job, to play unity, mutual help support the spirit of love. Second, improve and maintain boiler equipment, keep boiler room tidy, attention and strive to save coal, water, electricity. Third, in the boiler operation to maintain a predetermined pressure, temperature, pressure must not exceed. Pay attention to discern false water level. Bearing in mind the piping, valves and the valve opening position of the distribution status of operation. Gradually closing the valve should be open or closed on the side of the handwheel. Always pay attention to the old boiler malfunction and run accident precursor, should understand the reasons for treatment and prevention of its occurrence. When the need for urgent and emergency shutdown. Keep in mind the role of the distribution board each button, leaving no more than a total pressure during shutdown and cut off the power supply. Fourth, coal hopper raised or lowered, the lower non-coal hopper to stand, the suction air blower, fan, Java machine, near the transmission gear portion, careful attention to production safety, to prevent accidents. Fireman must stick to work, and offenders a fine deal. V. PREPARATION carefully, to prevent explosive materials
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
