2 ton gas steam boiler manufacturer
2tph WNS series gas-fired 2 ton steam boiler manufacturer project for feed industryTempering is a crucial link in the granulation process of feed industry; the performance of tempering has a direct impact on the quality of pellet feed. Currently, feed mills use steam to complete the tempering process; hence, a steam boiler is a core equipment for feed industry. Nanjing Shuaifeng Feed Co., Ltd. is established in 2005, its major products consist of aquatic feed, tubificidae, fish feed and crab feed. To improve the feed quality and response to global environmental policy, Nanjing Shuaifeng Feed Co., Ltd. planned to reintroduce an efficient and environment-friendly steam boiler. After a series of contrastive analysis on a lot of boiler products, the company was attracted by the high performance of ZOZEN WNS series gas-fired (oil-fired) boilers, and order one set of 2tph steam boiler. This kind of boiler has wide fuel adaptability, including natural gas, light diesel oil and much other clean energy; with low NOx burner, ultra-low emissions of nitrogen oxides can be easily achieved. Meanwhile, the boiler adopts a large-diameter corrugated furnace to ensure the full combustion of fuels; the sufficient storage areas of steam and heating surface can effectively improve the thermal efficiency of the boiler as well as the the quality of outlet steam.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing 2 ton steam boiler manufacturer for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
In the national standard of water quality standard, the water quality index of hot water boiler stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired 2 ton steam boiler manufacturers have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.
The advantages of gas 2 ton steam boiler manufacturer Gas steam boilers advantage: designers will arrange commandment information again, simple and convenient operation of the facility. Gas-fired steam boiler is not only easy to operate, and as soon as possible to ensure the safety factor used. Energy-saving advantages: high-temperature gas steam boiler with characteristic base pressure, greatly reducing the use of water pressure level heating facilities, to immediately benefit from lower capital injection facilities. Also said that the proportion of raw materials and gas touched. Only proper and adequate oil ignited gas can produce ratios exceeding ignite rate, together with its ability to reduce vapor emissions and maintain two-way power-saving, very convenient. Gas steam boiler can be arranged according to the specific needs of the amount of vapor, reduce renewable resource conservation. The higher the specific requirements and the intermediate supply pairing methodology, the higher the power saving effect. The heat exchanger can continue to use sewage water calories, and thus can increase oxygen supply and drainage of water temperature. In accordance with the provisions of the Environmental Protection useless now need, doing everything, gas-fired industrial equipment is more commonly used. In severe conditions, serious vapor watering, the water content of the salt to enhance the micro gas steam boiler, water hammer audible in steam lines, steam splashing outwardly coupling joint living; or furnace tube if economizer line split, water vapor allowance is given below, when less water is generated, in turn, the situation will occur; less water when severe, it is possible to see the red water wall of furnace tubes can also smell burnt taste. Together, furnace tube will split, could hear explosions. Steam and smoke exclude the furnace mouth and fire security door from. Low water interlock device, if the amount of water is less than the target value, air-conditioning fan, booster fan and grate machine motor reducer operation should be terminated; Security Council water is less than the low water mark, water glass (plate) is black; cleaning sheet is not water clear micro gas steam boiler is not filled or slightly severe filled with water? Ways: first turn off the water level gauge, tap water pipe is connected, and then open the drain cock. If you can see the water line from the top lower, then it is filled with a little water, open the drain valve and place no problem of water. If severe filled with water, please use the emergency shutdown countermeasures.
