With outstanding advantages of the comprehensive performance of the SHX circulating fluidized bed steam boiler, ZOZEN became the coal-fired boiler supplier of Sanming Fengrun Chemical Co., Ltd. Founded in May 2005, Sanming Fengrun Chemical Co., Ltd. is a main pharmaceutical and feed carrier silica manufacturer engaged in the production and sales of silica (white carbon black). Its products are widely used in shoe soles, silicone rubber, green tires, pharmaceutical carriers, feed, food and other industries. The ZOZEN SHX circulating fluidized bed steam boiler can meet all the requirements of Fengrun Chemical on the production line in terms of efficiency and environmental protection and improve its economic benefits.
We conducted a rigorous market research on the industrial boiler market before purchasing the boiler. Finally, we selected ZOZEN which had good boiler quality and professional services. At present, ZOZEN WNS series gas-fired steam boiler had become an important part of our production line. The feature of automatic operation greatly saved labor costs for our company.
The industrial boiler is very important for garment production lines of Shenzhou Knitting, which will directly affect the product quality and output. With advantages of boiler performance, ZOZEN became the heat source equipment supplier of Shenzhou Knitting and completed the manufacturing, installation and commissioning of the SZL series chain grate steam boiler. The boiler adopts a desulfurizer, a denitrator and an online monitoring device to achieve standard flue gas discharge. In addition, this series of boiler is a horizontal double-drum chain grate boiler. The furnace is composed of water-cooled wall, front arch, rear arch and furnace base. The large furnace not only reduces the heat load but also reduces furnace coking. Meanwhile, multiple independent wind chambers and air adjustment devices are equipped at the lower part of the boiler grate to supply enough air for fuel combustion. And, the fuel utilization rate is improved through precise air distribution. Besides, the SZL seri
Jiangsu Hengtong Printing and Dyeing Group Co., Ltd. set high requirement for the automatic operation and safety of the thermal oil heater which had great importance to its production line. After rigorous market research, Hengtong purchased a set of ZOZEN YQW series gas-fired thermal oil boiler in 2018. Equipped with an advanced burner, this series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PlC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface. In addition, the boiler has been in stable and high-efficient running since its operation, which was highly praised by Hengtong. This time, with the expansion of the production scale, Hengtong planned to get another thermal oil heater and cooperate with ZOZEN again.
Founded in 2007, Jiangsu Dalishen Science &Technology Co., Ltd. is mainly engaged in the research, development and production of aluminized zinc (steel coil), color coating (steel coil), high-precision silicon steel plates. With multiple (aluminum) zinc plating production lines, color coating production lines and silicon steel lines, Dalishen has constructed four phases of projects. This fifth phase of the project is a heat supply project for the high-precision silicon st...
Because of the characteristics of high temperature and low pressure, the thermal oil heater becomes an important piece of equipment of the fine chemical industry. Wuhai Shilian Environmental Protection Technology Co., Ltd. was established in April 2018. With a total investment of 320 million yuan, the company was a reorganization of Wuhai Black Cat Sanxing Fine Chemical Co., Ltd. After sufficient market research and technical demonstration, Wuhai Shilian decided to re-plan the product structure of the original company and invest a 20,000-ton-per-year phenol series technology transformation project including 10,000 tons annual output of resorcinol, which is mainly used for rubber adhesives.
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
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.
