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.
Among many industrial boiler products, Bintou Thermal Power selected ZOZEN SZS series gas-fired steam boiler for peak shaving. This series of boiler is designed with longitudinal double drums and " D " type chamber structure. The combustion chamber adopts a membrane wall structure, which has good air tightness, no smoke leakage, and high thermal efficiency. Meanwhile, the tail of the boiler is equipped with flue gas condensation recovery devices to effectively control the exhaust temperature and increase the thermal efficiency to more than 98%. In addition, devices such as explosion-proof doors, flame detectors, water level alarms and water level interlocks are equipped to further ensure the safety of boiler operation.
ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
With features of low pressure and high temperature, ZOZEN various series of thermal oil heaters have become heat source of many chemical enterprises. ZOZEN YLW series coal-fired(biomass-fired) thermal oil heater is a square coil horizontal chain grate shop-assembled heater of which the chain grate and heater proper are transported separately. Once connected the oil and electricity, the heater can be put in use. This series of heater adopts an advanced structure, including four parts: the radiation furnace heating area, convection tube bundle heating area, waste heat boiler and air heater, which has sufficient heating area and ensures high thermal efficiency of the boiler. Meanwhile, ZOZEN reasonably designed the combustion chamber according to different characteristics of different types of coal and biomass fuel, which not only ensures the complete combustion of the fuel but also improves the combustion efficiency and reduces the formation and emission of flue gas. This series of heate
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 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.
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%.
