Hot Sale Coal Fired Hot Water Boiler
In early 2013, fast boiler is a food processing company Luohe a 10-ton condensing steam boiler installed integrally cloud service monitoring module, by monitoring the data found in March, the maximum pressure in the boiler set small deviation, the small boiler load adjustment range, and it uses a continuous replenishment way. When such a large load changes, the burner will start and stop frequently, adversely affect the boiler. After the burner system to monitor working properly, timely communication with customers, to help customers put pressure adjusted to the maximum deviation of the normal range. Then return to the display data safe range, the maximum starting frequency is reduced to the burner 4 times / hour from 8 times / hour, reduced by the mean starting frequency of 3.7 times / hr 1 / hr reported in June. At the same time gas consumption decreased by 10% to obtain the customer's trust and recognition.
In recent years, vigorously promoting the "coal to gas" national project, in northern China have started to use gas hot sale coal fired hot water boiler to provide heating and hot water for residential, hotels, hospitals, shopping malls and some entertainment.
10tph WNS fire tube boiler project for new energy industrySteam, as a kind of energy, is widely used in all walks of life. Longzheng Environmental Protection Technologies Co., LTD. is a new high-tech enterprise applying a number of energy-saving technology including biomass molding pellet combustion technology, water coal slurry combustion technology and natural gas combustion technology to provide pure steam for food, pharmaceutical, textile and other industries. Therefore, a steam boiler acts as the heart for the enterprise; it is important for the production line that the steam boiler runs stably for a long time. The "Green Revolution" has become a global trend recently; Longzheng Environmental Protection Technologies Co., LTD. takes an active part in environmental protection, the companies decided to obsolete previous boilers with excessive emissions and introduce several sets of natural gas fired steam boilers. ZOZEN, one of the most influential boiler manufacturers in Asia, customized a comprehensive boiler solution for Longzheng Environmental Protection Technologies Co., LTD.: ZOZEN recommended 4 sets of 10 tph WNS series gas-fired steam boilers for the company based on their actual demands for steam. This series of boiler adopts a large-diameter corrugated furnace to increase furnace heat transfer area, ensuring the stable running of the boilers. In addition, the boiler is equipped with a low NOx burner to reduce the NOx emission to 30mg/Nm3; furthermore, ZOZEN also installed economizer and condenser on the tail of the gas-fired boiler, which will effectively reduce the exhaust gas temperature below 60℃ and improve thermal efficiency up to 98%.
Maintenance and installation instructions boiler environmental protection boiler water clean-up at least once a month: on the furnace grate string of pipes and water pipes at the water cross scale. Always check: valve, pipe, flow is flexible door sheet intact, to prevent clogging, damage should be found to repair and restoration. Cleaning at least once a week, and the boiler flue gas path surface fire, arch wall, Guanfan, pipe tobacco, soot and smoke chamber grime, etc., to keep the heating surface clean, stable heat transfer. When the water heater and heating system is installed, the main line and the last two are not allowed to just valving. Other air bag inlet pipe may be installed at each branch for adjusting the control valve system balance, the smaller is generally the closer the opening degree from the furnace, whereas the more distal opening degree increases. When the valve opening is adjusted to the proper position, not twist, so as not to influence the heating effect. Fill the tank water heaters is open, its role with the expansion tank. Prohibit any valve mounted on the furnace body and connected to the tank conduit. Usually the main pipe heating installation slope i = 0.005. Riser mounted to the vertical, per meter length of not more than 3 mm. A normal heating boiler water temperature should not exceed 85 ℃, such as the temperature exceeds the complement in order to continue running when the tank overflow tube or overflow a large number of air, immediately check the hot water circulation system shutdown has blocked until troubleshooting. When the water level inside the heating supply water should be kept in a glass of water gauge water line visible range, prohibiting see cast coal burning furnace at less than the case of the water level in the water gauge glass, causing the system to prevent water shortages. Boiler installation location should be close to a hot spot closer a distance as possible to reduce heat loss. Piping system may be depending on the use. Water heaters based on the principle of gravity circulating water, due to the small circulating water gravity pressure head, and therefore, the installation must be less than the last group of the furnace heating bag, the vertical distance is generally 0.5-1 meters.
