Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial steam boiler as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
The scaling of gas-fired steam boiler not only reduces the thermal efficiency of the boiler, but also increases the temperature of the heating surface of the boiler, causes damage to the heating surface, and even causes the explosion accident of the boiler. Therefore, the use of soft water treatment equipment, strictly according to the process operation of boiler feed water softening treatment equipment, control boiler feed water quality, can delay the formation of the scale. At the same time, it is very important to control the boiler scale in real time, master the boiler scale and clean the scale if necessary. Because the temperature of the gas-steam boiler body and the steam-water heat pipe system is higher than the air temperature in the boiler room, some of the heat is emitted through radiation and convection into the surrounding air. This becomes a loss of heat. Boiler Therefore, the heat loss should be reduced when the heat insulation and heat pipe system of the boiler are damaged or leakage is discovered. The increase in noise from gas-fired steam boiler burners is mainly due to the closure of the valve or insufficient oil intake in the oil path, blockage of the oil filter, or because of low inlet temperature, high viscosity or oil on the pump. Too high temperature; oil pump failure; fan motor bearing damage; due to dirty turbine impeller, the equipment is too loud. This failure occurs when a gas-fired boiler is in use and is not easy to atomize (heavy oil) because of the high viscosity of the oil; it is also due to cyclone and jet The distance between the nozzles is inappropriate; in addition, because the burner is worn or dirty; it is also due to the excessive heating temperature of the spare fuel tank, resulting in steam pumping the oil pump out of the oil pump; or because the oil in the oil boiler is hydrated. Gas steam boiler feed water contains a variety of impurities and calcium, magnesium and other scaling substances, the boiler will inevitably expand. The thermal conductivity of the scale is very low, so once the surface is polluted by the hot surface, the exhaust temperature of the boiler will increase, and the heat loss of the exhaust gas will increase due to the increase of the thermal resistance. The experimental data show that the heat loss of waste gas will be increased by about 2%-4% when 1mm oxide is formed on the heating surface of boiler. The thicker the scale on the heating surface of the boiler, the greater the thermal resistance, and the lower the thermal efficiency of the boiler.
Category Description oil-fired boiler fuel gas-fired boiler is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. If the hydrocarbon injected into the furnace with the air mixing within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a chassis, the assembly may also be medium-sized factory. Boiling water boiler fuel oil boiler fuel, also known as water heaters, stove oil, furnace fuel tea, water boiler fuel, is living in a boiler, belong to the category of civilian atmospheric boiler. The boiler is a fuel oil as fuel by a burner to heat the water, when the water temperature reaches the set temperature (water), the burner stops working, heat boiler into the automatic state, the user starts to provide water, oil and water if the boiler holding tanks connected to meet like hospitals, schools and other centralized water supply demand type units. Hot water boiler fuel oil china manufacturer fire tube hot water boiler for hotel fuel refers to fuel have mainly boiler fuel hot water boiler with a high-tech automatic control system, with a number of security devices, water protection, overpressure protection, flame protection abnormal pressure protection, over-temperature protection flue; using high-tech structures, having a body holding a small, compact and easy to install, simple operation, automatic adjustment, the pressurized fuel to the atomizer, and then allowed a slight positive pressure fuel combustion burner more fully, to reduce the loss of gas emissions and fuel, it is a modern industrial steam to use the most convenient and most energy-efficient, environmentally friendly standard products. Fuel steam boiler fuel (gas) steam boiler, a horizontal combustion all wet back, efficient threaded pipe, with a sound insulation outsourcing design, the boiler thermal efficiency as high as 85% or more, product design, rational structure, process performance is good, so that this product has extraordinary excellent quality.
The invention and use of boilers have a long history, and the use of condensing boilers, to a certain extent, makes full use of the heat of flue gas and water vapor itself, which is a more environmentally friendly way. And all-in-one condensing boiler price is fair. However, in the process of operation, maintenance is needed to ensure the stability of the operation. The following three aspects should be paid attention to in the daily maintenance of the condensing boiler.
1, attention should be paid to the maintenance of boilers as required to a large extent in order to check and detect the existence of problems in condensing boilers in order to be able to solve or prevent problems in a timely manner, and this will also avoid further expansion of the problems. It protects the furnace from further damage and should be careful not to add antifreeze in the water. All premixed aluminum condensing boiler manufacturers introduce that if the newly installed condensing boiler system should be thoroughly flushed, the remaining oil paper or metal debris and other impurities in the boiler should be removed.
2, pay attention to the fact that this step of installing filters is indispensable and can largely prevent the boiler from being damaged. Some preparations should be made before the condensing boiler is opened for official operation. Water circulation, for example, should take up to two hours so that impurities can be removed first. Condensing boiler manufacturers also remind after the end of operation, should be timely to open the safety valve, further removal of impurities inside.
3. Pay attention to cleaning work before installation. Before installation, special additives are also needed to clean all pipes. And condensing boiler manufacturers emphasize that cleaning agents must be neutral and absolutely not to have any acidity or alkalinity in order to avoid corrosion to the equipment. In short, it should be done according to the requirements of the manufacturer. Because the materials of ordinary condensing boilers are silicon-aluminum alloy, so they are very sensitive to alkaline substances, so the ph value of hot water in the boiler should never be controlled within the prescribed range of mixed additives must be prescribed by the manufacturer. You can't use other types at will.
