Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
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.
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
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.
The winter in Liaoning Province is long and cold. As an important heating device, the stability of the boiler operation will directly affect the life of the people. In order to successfully complete the central heating task in winter, Huludao Longgang District Heating Co., Ltd. , held an open bidding in the whole country for the coal-fired hot water boiler. The coal-fired hot water boiler produced by ZOZEN is famous in the northern boiler market for its excellent performance, reliable operation and friendly environment protection. Huludao Longgang District Heating Co., Ltd preferred ZOZEN boilers and ordered 2 sets of DHW series coal-fired boilers.
Steam boilers are essential in large hospitals, which are used to sterilize and disinfect medical equipment, hospital bed sheets, quilts, etc. and provide steam for washing machines and dryers in hospitals. Nanyang Second General Hospital is a three-level general hospital with more than 2,000 beds and over 80 clinical and medical technology departments. Therefore, the hospital has a large demand for steam. In response to the national green development concept, People's government of Henan province decided to repurchase a gas-fired steam boiler for daily sterilization and disinfection. Serving as a place of healing the wounded and rescuing the dying, the hospital has high requirements for the quality of steam and the stability of boiler operation. The project leader of Nanyang Second General Hospital was attracted by ZOZEN's perfect production line and strict quality supervision after inspecting many well-known boiler plants.
In the corrugated paper processing line of the packaging industry, the steam boiler is an important heating system for increasing the temperature of the paperboard and is one of the essential equipment. Founded in 1995, Fijian Nanan Lianfa Paper Industry Co., LTD. attached great importance to technical input and strictly controlled product quality. At the same time, they knowed thoroughly that the efficiency of boiler operation would directly affect the company's product quality and economic benefits.With the fierce market competition, Lianfa Paper decided to eliminate backward production capacity and introduce high-quality and high-performance environmentally friendly gas-fired steam boilers.
Xinzheng Heli Thermal Co., Ltd. is a company specializing in heat energy production and central heating supplying, providing heat source for winter heating for people in Xinzheng . Facing the increasingly serious environmental problems, Xinzheng Heli decided to respond positively to the "coal to gas" policy, using clean energy natural gas as boiler fuel and introducing high efficient gas-fired boilers to replace the original coal-fired boilers. For this, Xinzheng Heli Thermal carried out an open bidding. After competitive bidding and strict selection,ZOZEN defeated other competitors and won the bid with its comprehensive corporate strength. The winning bid was ZOZEN energy saving and environmental protection product - SZS series condensing gas-fired superheated steam boiler (3 sets of SZS75-1.6-Q). The furnace and the front and rear walls of this series of boilers adopt membrane water wall structure, and the airtightness is good.
