Worldon (Vietnam) Co., Ltd. is an overseas project of Shenzhou International Group and is a clothing company with the concept of green production. The company, fully established and put into production in 2016, mainly produces the knitted garments of international brands such as Nike, Uniqlo, Adidas and so on. In order to meet the increasing production demands and cut the production costs at the same time, Worldon (Vietnam) Co., Ltd. successively purchased 3 sets of high-efficiency and energy-saving SZL series chain grate coal-fired steam boiler from ZOZEN, which effectively improved Worldon's production capacity and product quality, and also realized the goal of energy saving and emission reduction to help Worldon fulfill the green production.
The new process using the ethylene oxide method has low production costs and stable product quality, however, the yield of the ammonification process and the production continuity are the key points in the process. Therefore, Jiangyin Huachang Food Additive Co., Ltd. has set clearly high requirements for the entire boiler system. ZOZEN Boiler tailor-made the design of the YQW+WNS series boiler system project in order to meet the sufficient and continuous heating source support of the food additive production line. Among them, the body of YQW series gas-fired thermal oil heater adopts three-pass round coiled tube structure, with sufficient heating surface, and the energy-saving device installed at the end of the furnace can ensure the thermal efficiency up to 95%. The advanced combustion device can realize low NOx emissions of the entire boiler system, meanwhile ZOZEN Boiler has equipped the automatic control system to ensure the continuous and efficient operation of the heating source
After the boiler was put into operation, the WNS series gas-fired hot water boiler would provide a stable heat source for the heating of agricultural greenhouses and living areas in our Science and Technology Park. The characteristic of high efficiency will greatly reduce our costs of heating supply.
We were very satisfied with the ZOZEN gas-fired thermal oil heater which fully met the actual requirements of our production lines. In addition, the automatic control system was easy to operate, which greatly reduced the operation costs and improved the economics benefits for us.
During the production of Alpha GPC, the process of evaporation and concentration requires high temperature steam provided by steam boilers. In order to respond to the call of clean production, Foman Biopharma selected a set of ZOZEN boiler which used natural gas as fuel. Meanwhile, ZOZEN customized the WNS series gas-fired boiler solution according the actual steam needs of Foman Biopharma. This series of boilers are wetback fire-tube boilers. With a three-pass design, the boiler adopts a large-diameter corrugated furnace. A combination of threaded flue tubes and smooth flue tubes is designed to increase the flue gas flow and optimize the heat transfer effect.
Besides, energy saving devices are equipped at the tail of the flue to fully absorb the heat energy and improve the thermal efficiency of the boiler to more than 98%, which can reduce operating costs for Foman Biopharma.
This series of thermal oil heater can realize low-pressure and high-temperature heating by utilizing the characteristics of the thermal oil heater. The high thermal inertia can effectively maintain the temperature uniformity during the food heating process. This thermal oil heater has outstanding energy-saving effects and low operation costs. It adopts closed-loop circulating liquid phase to transfer heat energy, the heat loss of steam boilers such as heat running, dripping and leaking can be avoided. Meanwhile, a complete operation control system and safety monitoring devices are equipped to precisely control the working temperature. It was the mix of these advantages that effectively reduced the production costs and improved the production safety of Changling Food.
ZOZEN SZL series gas-fired boilers with excellent quality and outstanding performance has become the heat source equipment of many enterprises of the paper industry. This series of boiler adopts D-type arrangement and water tube structure. The large-volume combustion chamber has good air proof and ensures complete combustion. Meanwhile, good quality alumina silicate fiber and fire clay insulation material are used to control the boiler body temperature below 45℃, and greatly heat loss is reduced. Energy-saving devices are equipped at the end of the boiler to increase the thermal efficiency to above 98%. In addition, SZL series gas-fired boilers are easy to operate. Advanced PLC intelligent control systems with various protection functions such as automatic water supply, program ignition, over-temperature control and over-pressure control can reduce costs for enterprises.
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
