With increasingly stringent environmental protection policies, coal-to-gas boiler projects are progressing in an orderly manner across the country. In this process, ZOZEN WNS series gas-fired steam boiler with excellent environmental performance has been widely recognized and favored by the market. This series of gas-fired boilers adopts a large-diameter corrugated furnace, which can not only ensure the full combustion of the fuel to a certain extent, but also effectively absorb the thermal expansion. And the threaded smoke tubes have good thermal scalability, scientific airflow design, effectively absorb the flame heat, and combined with the energy-saving devices at the end of the flue, the boiler thermal efficiency can reach over 98%. In addition, in response to the low NOx emission requirements put forward by more and more enterprises, ZOZEN has selected international advanced low NOx burners to easily achieve NOx below 30mg/Nm3, and customized a full set of boiler system design sol
In the production process of foam packaging materials, the foaming, molding, drying and other technological processes require the stable steam generated by the boiler. Xin'an Baolilong Packaging Co., Ltd. specializes in the production of foam products, mainly used for the packaging of electrical appliances, furniture and a variety of building materials. With the development of the society, the market demand for foam packaging products continues to increase, Baolilong Packaging decided to expand production capacity and introduce a new gas-fired steam boiler. BaolilongPackaging put forward the requirements for the boiler: safety, environmental protection and high efficiency.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
In the heavy machinery manufacturing industry, the processes of smelting, pouring, and producing finished castings consume a large amount of steam. ZOZEN superheated steam boiler can meet the temperature requirements of these process.
SZL series steam boiler is a longitudinal double-drum chain grate water tube boiler designed by ZOZEN on the basis of advanced international technology and its own experience. 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. the combustion air system (base) adopts independent compartment and scientific sealing structure; reasonable air conditioning device improves combustion efficiency. The water membrane wall, the front and rear arches and the hearth constitute the boiler furnace, A bank of return convection tube bundles are arranged at the rear of the boiler body to sufficiently absorb the heat released by the combustion. The SZL series chain grate steam boiler system customized by ZOZEN has excellent performance and the thermal efficiency is more than 5% higher than the similar boiler system on the market.
The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital. Hot water and steam are essential energy sources for large comprehensive hospitals, providing adequate steam heat energy support for hospital heating and daily disinfection. Under the background of current energy-saving emission reduction and refined management, the Second Hospital of Jilin University actively responded to the national “coal to gas” policy and decided to replace the old boiler equipment with low efficiency and high emission.
Steam boilers are the important heat source equipment in the plastics industry, providing sufficient heat for polymerization, dehydration, drying and thermoforming processes. JJS SRL is a Chilean company with more than 40 years of experience, specializing in the production of polyurethane products for a wide range of industries. Temperature is a critical factor in the production of polyurethane products. Generally, the polyurethane reaction temperature is controlled between 60 and 100 degrees. If the temperature is too low, the reaction rate will be very slow, which is not conducive to the reaction. Therefore, the stable operation of steam boilers plays a vital role in the enterprise.
