Founded in 1994, Harbin Investment Group Co., Ltd. is mainly engaged in production and supply of electricity and heat. The SZS series gas-fired package boiler purchased by public bidding performed well both in environmental protection and thermal efficiency. Adopting D-type arrangement and water tube structure, the boiler is equipped with a big combustion chamber for the full combustion of fuel. Advanced low NOx combustion technology is combined to reduce the
NOx emission to 30mg/Nm3. Combustion chamber is designed with narrow distance full membrane water cooling wall which has good air proof and high thermal efficiency. Meanwhile, the flue gas condensers equipped at the tail of the boiler can effectively control the flue gas temperature, increasing the thermal efficiency of the boiler to over 98%. Besides, the package delivery feature of SZS series gas-fired boiler greatly reduced infrastructure cost
ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
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.
In the production process of chemical products, the refined processes including salt forming reaction, condensation reaction, desolventizing and drying have specific requirements for the temperature, hence, the boiler is an essential piece of equipment in chemical industry. Jiangsu Aolunda Technology Industrial Co., LTD. is a new high-tech enterprise specializing in developing and manufacturing functional fine chemical products that are exported overseas. All along, chemical enterprises are often heavy polluters. As a enterprise that has the courage to undertake the social responsibility, Jiansgsu Aolunda decided to upgrade the production line equipment to deal with the increasingly serious situation of environmental protection. As one of the important equipment of the production line, the boilers had to be replaced with more energy-saving and high efficient ones in an urgent need.
Jiangsu Aolunda had already heard about ZOZEN before and decided to conduct a field visit to ZOZEN in Yi
A steam boiler plays an important role in production and processing, and is widely used in all walks of life. Founded in 1987, Thai Glucose Co., Ltd. is a professional manufacturer of glucose syrup, fructose syrup, dextrose monohydrate and other special specifications. A steam boiler is the indispensable important experiment device of its production line, providing sufficient steam for the production processes of purification, evaporation and drying. The previous steam boilers had obvious shortcomings in the output and quality of the steam, which had a significant impact on its production capacity. To ensure the product quality, Thai Glucose decided to import one set of high-performance biomass-fired steam boiler. ZOZEN won the trust of Thai Glucose with its excellent product quality and outstanding product performance. ZOZEN provided the company with one set of 6 tph SZL series biomass-fired steam boiler. This kind of boiler has wide fuel adaptability, is suitable for a wide variety o
In the production process of fine dried noodles, the stream boiler is a key equipment to provide plenty of steam for cooking, drying, concentrating, sterilizing and other production processes. Chen Keming, the founder of Kemen Noodle Manufacturing Co., Ltd. started the research and production of fine dried noodles since 1984. Currently, Kemen Noodle Manufacturing has developed into the leading private food hi-tech enterprise in the domestic noodle industry; its annual production capacity c...
Steam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. Ltd is one of large paper mill in Thailand, producing pulp, mechanical pulp, paper, board. Steam is an essential element in their production process. With the expansion of business and scale, the paper mill's demand for steam is increased by years. Therefore, Thai Development Industrial Paper Co. Ltd needs to order several sets of new steam boilers. Coal is used to be the boiler fuel in this paper mill so that they pay great attention to the combustion efficiency. After knowing their actual situation, ZOZEN’s sales manager has supplied 15tph SZL series water tube steam boilers for the company. This series of steam boiler is adaptable for all kinds of coal. Unique chain grate produced by ZOZEN is adopted for the fuel to be fully burned. Meanwhile, rational air register is designed to improve combustion efficiency.
ZOZEN is so professional that the boiler they recommended is based on our actual need. The gas-fired steam boiler will increase the fuel costs because of the expensive gas. But the boiler provided by ZOZEN is designed to have high thermal efficiency, helping us saving the fuel costs. The fully automatic safe operation design also helps us save the running costs. We are really appreciated for ZOZEN’s products.
