industry dual fuel steam boiler

15 tph WNS condensing gas-fired boiler for food industryHenan Youmai Food Co., Ltd. is part of the White Elephant Food Group and was established in 2013. It mainly develops, produces and sells "White Elephant" and "Youmai" brand noodles. Noodle drying process generally has rapid drying at high temperature, slow drying at low temperature, and medium-speed drying at medium temperature.Noodle drying is also the most invested and technically most productive process in the entire production line, and has a very important relationship with product quality and production cost. The occurrence of crispy noodles, tidal noodles, acid noodles and other phenomena in production are all caused by irrational drying equipment and technology. Therefore, White Elephant Food attached great importance to the purchase of boiler equipment for Xinzheng Factory. In 2017, White Elephant ordered 15 tph WNS condensing gas-fired boiler at ZOZEN. The front and rear smoke boxes of the boiler are filled with multi-layered aluminum silicate fibers and then insulated with high-temperature fire-resistant mud to increase the thermal resistance, effectively reduce the heat loss and improve the thermal efficiency.

Advantage of Water Tube Boiler

Water tube and fire tube boilers are essentially the opposite in design. In a water tube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. In a fire tube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Fire tube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a “pass”. Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front. A boiler with more passes has a higher heat extraction rate and is more efficient then one with less passes.

To antifreeze to choose according to the specific case of a small gas industry dual fuel steam boiler plumbing system according to the temperature selected for the small gas steam boiler antifreeze. Small material gas steam boiler and plumbing system made of aluminum alloy should be used in antifreeze silicates, for the system of cast iron, it is necessary to add corrosion inhibitors, PH value is adjusted between 8-9; To purchase by the National designated testing station tested and antifreeze products, the use of substandard product causes corrosion of the heating system. If small gas steam boiler plumbing system had not using antifreeze, before adding antifreeze to flush plumbing systems; to choose a different freezing point of antifreeze according to the temperature region of use antifreeze. Antifreeze freezing point should be lower than the historical low temperature in the region of 5-10 ℃; can not mix different brands of antifreeze, so as not to damage their overall corrosion resistance. Small gas steam boiler after a period of use, antifreeze will be deficient, then first check the density of antifreeze. If small gas steam boiler antifreeze density is not increased, which is caused due to the leakage should be added for the same grade antifreeze; if the density is decreased, which is caused due to water evaporation, should be added to distilled or deionized water.

To further promote air pollution control tough fight, push the air quality continues to improve, according to "Zhengzhou City, the 2018 campaign of air pollution control plan" and "Chung Dong New Area, the 2018 campaign of air pollution control plan" requirements, the area to carry natural gas boiler low nitrogen renovation work, hereby notify the relevant issues as follows:

(1) before the end of September 2018, Eastern 4 tons of steam boiler and above the implementation of low-nitrogen gas engineering construction and renovation. Encourage the implementation of other gas-fired low-nitrogen transformation.

Promote the transformation of low nitrogen gas boiler according to early completion, and more reward principles, decreasing year by year funding award up mode. Before the end of June 2018 to complete the construction of low-nitrogen transformation, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 40% of equipment investment; before the end of September 2018, to complete the low nitrogen renovation project construction, the concentration of nitrogen oxide emissions or else higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 30% of equipment investment; before the end of April 2019 to complete the project construction and renovation of low-nitrogen, nitrogen oxides Or emission concentration higher than 30 mg / cubic meters of gas boilers, carried out in accordance with the award make up 15% of equipment investment;

After construction is completed, the project in a timely manner to submit an application to the territorial review township (town) office: the township (town) office on a preliminary review of the whole process of the project, the project area through on-site verification of materials (including: project implementation plan, completion report, monitoring reports, on-site verification opinions, etc.) reported the construction of the Environmental Protection agency, the EPA reported by the construction of the Municipal Environmental Protection Bureau atmosphere, the atmosphere at the Municipal Environmental Protection Bureau organizations to monitor third-party monitoring mechanism for acceptance, qualified after monitoring the municipal government finance awards complement funds, unqualified deadline for rectification.
