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.
With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control. Meanwhile, when the system pressure exceeds the specified value, the full lift spring-loaded safety valve will be automatically opened to release pressure, which can avoid the accidents caused by excessive pressure. In addition,the chain grates of this series of boiler are all manufactured by ZOZEN. A 72-hours test run of the chain grates can ensure the moderate tightness of the grate. Besides, the scientific grate arch design, reasonable air distribution and governor box speed ensure the full combustion of biomass pellet fuel and the overall thermal efficiency of the boi
A safe and high-efficient thermal oil heater is very important to an enterprise, which directly affects the product quality and the economic benefits. In November 2017, the burst of the pipeline of the existing thermal oil heater triggered a fire at Jiangxi Huachen Spice Chemical Co., Ltd. The fire caused considerable losses to the enterprise. Immediately, the leadership of the enterprise decided to repurchase a set of high-quality thermal oil boiler. With good market reputation and strong company strength, ZOZEN got the trust of Huachen Spice. ZOZEN YQW series gas-fired thermal-oil heater has excellent safety performance. The functions of over-temperature alarm, low oil level alarm and over-pressure alarm can ensure the stable operation of the heater. In addition, because the inner coil of the radiant section of the heater absorbs much more heat than the middle and outer rings, ZOZEN designed a large flow rate inner coil to ensure the safe and reliable operation at high temperature.
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%.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
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
