This SZL series boiler is designed and developed by ZOZEN, which has the characteristics of wide adaptability of coal type, compact design and convenient installation. Benefiting from its outstanding performance advantages, this series of chain furnaces successfully won the favor of Agra Feed S.A.S. In order to improve the actual efficiency of the company, ZOZEN also customized a complete set of steam boiler system with a thermal efficiency of over 82%. Meanwhile, according to the environmental protection requirements of the region, ZOZEN also installed dust removal, desulfurization and denitration facilities to effectively reduce NOx emissions.
The production process of liquid dairy products mainly includes: raw milk acceptance, milk cleaning, refrigeration, preheating, homogenization sterilization, cooling, aseptic filling, fermentation, final product storage etc. Steam boiler is used for fermentation, disinfection, drying, etc., Recently, Wuwei Yili purchased 3 sets of ZOZEN 15tph WNS gas-fired boilers.
ZOZEN customized the gas-fired hot water boiler system, and recommended several sets of SZS series natural gas fired hot water boilers, which had the characteristics of sufficient output, high thermal efficiency and stable operation. This series of boilers is designed with longitudinal double drums and "D" type chamber structure.
Bolivia is the highest average altitude country in the world, local Bolivian companies have higher requirements for boilers than general boilers. As the altitude increases, the atmospheric pressure and the air density decrease accordingly, which adversely affects boiler combustion.
In view of this situation, ZOZEN technical team makes adjustments from the combustion system and exhaust system of boiler, fully considering the influence of low air pressure on boiler body design and combustion. By appropriately increasing the volume of the furnace to extend the residence time of the fuel in the furnace, and the problems of slow fuel burning speed and long burning time are solved.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency. In addition, the water circulation structure of DHL series coal-fired boilers is identified the first domestic product in China due to its reliability and advancement. It is widely used because its comprehensive performance has exceeded similar products on the market.
Steam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. SZS gas-fired water tube boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to 30mg/Nm3.
