Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast boiler R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.

(3) According to the boiler technical standards: strictly control the normal water level of the boiler to prevent the steam from being watered due to the high water level, resulting in deterioration of steam quality. In addition, avoid sudden increase or decrease of load, so as to avoid the occurrence of false water level, causing a sharp increase in water level and serious deterioration of steam quality.

4 tph WNS series gas-fired fire tube boiler project for food industrySteam boilers play a key role in the production and processing of pressed vegetable, providing heat source for emulsifying and sterilizing. Chongqing Fuling Zhacai Group Co., Ltd. is a large-scale agricultural industrialization enterprise group, its leading products Wujiang series pressed vegetable is widely known and sold well in China, and has exported to many regions and countries such as the European Union, the United States and Japan.As the environment pollution has become more and more serious in recent years, Fuling Zhacai decided to upgrade its existing equipment, promoting the transformation of pressed vegetable exploitation and utilization from extensive form to intensive and environment friendly form. Fuling Zhacai was in desperate need of introducing more environmental friendly boilers to ensure the NOx in flue gas emission below 30mg/Nm³, the boilers are the important facilities of the production line. ZOZEN stood out in the in the competitive bidding competition with rich industry experience and systematic Solutions and provided Fulin Zhacai with 2 sets of 4 tph WNS series gas-fired steam boilers (WNS4-1.25-Q). This series of gas-fired boilers adopts full corrugated furnace to enhance the flue gas disturbance; large-capacity furnace ensure the sufficient steam storage space and heating surface, enabling the boiler to generate high quality steam efficiently; the boilers is equipped with a low NOx burner to achieve the NOx emission below 30mg/Nm3; in addition, the tail of the boiler is installed with the economizer and condenser to increase the temperature of the feed water by utilizing the waste heat from flue gas of the boiler tail, the thermal efficiency can be raised up to 98%.

One of the important parts of the boiler - comprising a unitary structure drum boilers and boiler auxiliaries two parts. In the boiler body, the two most important parts of a drum and furnace. We have previously explained before the hearth, and today we take a look at the drum it. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. Its main function is storage, a water separation, to exclude the water pan and brine sludge in operation, avoiding pot containing a high concentration of salt water and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In use, the drum often go through thermal balance test, the time to consider the actual benefits of the boiler room, not only depends on the boiler thermal efficiency, energy meter and the auxiliary boiler also consumed. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in the flue gas of the drum, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Future development will further improve boiler thermal efficiency of boilers and power plants, increase operational flexibility and level of automation of the boiler unit, improve the operational reliability of the boiler unit and auxiliary equipment, which are inseparable from the drum.
