best industrial steam boiler for food industry
According to the rated output and boiler efficiency determined by boiler revamping, the fuel consumption is calculated, and the number of burners is determined according to the power of the selected single burner. Increasing the quantity of burners is beneficial to atomizing quality and ensuring air-oil mixing, but too much is not convenient for operation and maintenance, and it will also bring difficulties to the arrangement of burners. The adjustment range of burners should be large, which can adapt to the change of boiler load and ensure complete and stable combustion under different working conditions.
Prevention of boiler scale chemical plants What precautions boiler scale chemical plants which have 1 pot outside water. The method of treatment is the outer pot raw water before entering the boiler, wherein the boiler operation harmful substances through the necessary process processing with the aim of reducing calcium and magnesium ions in the boiler water to prevent boiler scaling and prolong the service life of the boiler. There softened water treatment, chemical, water desalination, heat, electrodialysis, and reverse osmosis desalination, four. Pressure in the boiler can be generally chemically softened water, high-pressure and ultrahigh-pressure boiler, to be deoxygenated and desalted water. In general, do not pollute surface water, hardness and alkalinity is very low, usually to soften; groundwater is very different, their common feature is the high alkalinity, therefore, should be considered in addition to softening in addition to usual bases; usually not required in addition to salt chemical boiler, only the high salinity water, generally soften, in addition to the base can not solve, in addition to considering salt, iron and high iron in groundwater. 2, the pot of water treatment and sewage. Boiler water is reduced by adding an amount of the boiler to prevent fouling or soft water, so that fouling material into boiler water sludge is then discharged from the boiler by blowdown. Treatment of the syrup, commonly used in small low pressure tube boiler, commonly used drugs are: trisodium phosphate, soda, caustic soda and organic colloids. The method of measurement points and two kinds of periodic continuous manner. Regular administration is usually carried out in a water tank, water was added continuously to the water before the water supply equipment. For best industrial steam boiler for food industry, by methods generally continuous dosing of the liquid in the boiler is more uniform. In general, the use of steam quality less demanding unit, in operation to ensure reliable exclude slag formed in the boiler, dirt formed by the dosing, the boiler will not affect the safe operation of the boiler can be carried out pot water treatment. 3, cleaning. Scale boilers can generally be divided alkali cooking (wash) cleaning, acid cleaning, mechanical cleaning three. Soda boiling boiler cleaning effect is designed to allow scaling, while its liquidity. Soda poor cleaning and scaling, often require complex mechanical descaling. Boiling descaling base have a certain impact on fouling sulfates and silicates, but the removal of the carbonate scale pickling far less. Caustic oven and cooking oil typically used to remove rust and installed on a new boiler, sometimes go to scale in the pickling or degreasing. Boiler should represent the sample size in advance before pickling tests, the cleaning solution; a start must be hanging box corrosion index (until the exit acid) as the acid in the boiler and acid; pickling process and the temperature of the pickling solution, such as concentration, flow rates, and control of pickling time should be achieved in accordance with the cleaning solution; the process should continue to clean and accurately recorded sample tests. 4, boiler operation and management. In the actual operation of the boiler, the boiler operation and management is an important means of preventing boiler scale. The operator shall establish the safety awareness of energy conservation, attention to boiler scale possible hazards and energy waste caused by learning the rules and regulations and national security specifications, attention to the operator (water treatment personnel and fireman personnel) training, develop effective rules and reward systems, regular testing work of the operator, even the best policy if not execution, it was only empty talk.
In the low profit era of Chinese paper packaging industry, entrepreneurs have been turning their attention to internal management, increase business efficiency by saving energy. At present, the paper packaging industry equipment many of them appear old and comes with a variety of issues, in particular energy use seriously inadequate problem is solved and bear the brunt of reform issues. So we must make an effort in the use of energy, use energy-saving equipment for the industry, in order to solve the problem fundamentally.
In the first step, the Fangkuai boiler opens the periodic main valve; (2) the boiler opens the primary valve first, and then slowly opens the secondary valve; (3) the boiler closes the secondary valve first and then the primary valve after the boiler has discharged the sewage; (2) the boiler opens the primary valve at first and then the secondary valve at the end of the boiler's discharge, and then opens the secondary valve at the end of the boiler discharge. Discharge should be slow to prevent water shock, if the boiler pipe such as vibration problems, it should stop the pollution, check the cause of the fault, until the fault repair in the discharge; (4) the Fangkuai boiler should stop the discharge immediately during the process of sewage discharge, such as the accident of the boiler, except that the drum water level is too high and the steam-water concurrence is common; The Fangkuai boiler forbids two boilers from discharging at the same time. The raw water of the Fangkuai boiler soften water equipment enters the control valve from the inlet, passes through the valve body from the upper part of the core, and enters the tank from the top (or outside the center tube of the resin tank, the same below). Then, down through the resin layer (this is softening, when purifying for the carbon layer, the same below) to become softened water, through the lower water distributor back to the center tube, up to the valve body, through the valve core after the discharge from the softened water equipment outlet. The raw water of the softening water equipment enters the control valve through the inlet, enters the inlet of the nozzle through the valve core, and flows rapidly to the outlet of the nozzle to generate negative pressure, thus making the salt The salt water in the tank is sucked into the valve body from the salt suction port and enters the top of the tank.
