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.
Founded in 1933, Luzhou North Chemical Industries Co., Ltd. is a comprehensive large-scale chemical enterprise. Its main products are military products, cellulose derivatives and silicone series. The production and processing of military and civilian products rely on the support of steam. Therefore, the boiler has become one of the important energy equipment on the production line.
Founded in 1991, Sichuan Liji Pickles & Flavouring Co., Ltd. is a large-scale agricultural and sideline products processing enterprise mainly engaged in the production of pickles, seasonings and red oil series dishes. In order to greatly improve production efficiency and effectively guarantee the stability of product quality, Liji Pickles & Flavouring introduced a series of automated production lines.

Chongqing Huabang Pharmaceutical Co., Ltd. is a joint-stock high-tech pharmaceutical company, mainly engaged in pharmaceutical manufacturing, medical and health. In the process of processing and pharmacy, the pharmaceutical factory needs a lot of steam to sterilize the drug, solid type, etc., then the steam boiler is an essential equipment. Therefore, there will be higher requirements for the selection of steam boilers. The WNS series of condensing boilers of ZOZEN boiler Co., Ltd. has a high energy-saving effect, and saves nearly 100,000 yuan compared to an ordinary gas-fired boiler. ZOZEN boiler has occupied a considerable proportion in the boiler market. In response, Huabang selected a 10-ton WNS gas-fired steam boiler for use in pharmaceutical production at ZOZEN boiler.
Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional Chinese medicine and natural medicine, integrating R&D, production, and sales. Traditional Chinese medicine pharmaceutical companies generally have extraction, concentration, distillation, drying, sterilization, purified water preparation, air-conditioning chillers and other technological equipment, all of which use steam as a heat source. However, at this stage, the general TCM companies do not use steam for comprehensive utilization. Steam is used only once, and a large amount of waste heat and waste heat are directly discharged into the atmosphere. The overall energy utilization rate is low. The person in charge of Junshan Pharmaceutical, through investigating and comparing the boilers on the market, finally chose to customize a 6-ton WNS condensing gas-fired steam boiler in the Zozen boiler to reduce boiler steam consumption and waste heat recovery, and increase the boiler ther
Jiangxi Copper Group is an ultra-large joint enterprise containing copper mining, selection, smelting in Chinese non-ferrous metals industry. It is also Chinese largest copper product production base and an important raw material for sulfide, and gold, silver and scattered metal producing area. As we all know, in the copper smelting process, a large amount of electricity and steam are consumed, and steam consumption accounts for about 30 to 40% of them. ZOZEN boiler has provided two 40-ton SZS condensing gas-fired boilers. The boiler adopts a D-type full-membrane wall structure, and the combustion chamber uses a narrow-pitch tube-type water wall, which has good sealing properties and reduces heat loss. The boiler body is made of high-quality aluminum silicate fiber and then kept in fire-resistant mud to keep the furnace temperature below 45°C and effectively control the heat loss.Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional C
