Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
China CEC Engineering Corporation is a large-scale engineering consulting and design company. Its main business covers engineering design, consulting, supervision and general contracting. It provides services for pulp and paper, energy and environmental protection, salt manufacturing and salt chemical engineering, household appliances, food, construction, municipal and other industries. In order to meet the demands of the project to construct a comprehensive PVC resin production plant with an annual output of 60,000 tons in Mekele, Ethiopia, CEC finally chose ZOZEN boiler as the boiler supplier for this project based on the investigation on the domestic boiler market. This time, CEC purchased 3 sets of SZL series coal-fired chain grate water tube steam boiler form ZOZEN Boiler who had completed the shipment recently.
Wuxi Pacific Fertilizer Co., Ltd., established in 1994, is a large-scale compound fertilizer manufacturer in East China. The company produces economical and high-quality compound fertilizers with great market demands and sales volume. Considering that compound fertilizers with high concentration and long effect have better market prospect, Pacific Fertilizer decided to enlarge the fertilizer production line via renewing the boiler equipment. After the field visits for a comprehensive understanding, Pacific Fertilizer finally signed the contract with ZOZEN Boiler to purchase a set of WNS series gas-fired steam boiler with sufficient output and high thermal efficiency as the heating equipment on the fertilizer production line.
Weifang Huabao Textile Co., Ltd., founded in 2004, is jointly invested by Changyi Huabao Textile Co., Ltd. and Hong Kong Aosen International Co., Ltd., which mainly engages in the weaving, dyeing and finishing of high-end fabrics. The steaming and drying processes of dyeing and finishing need a continuous and stable heat source. The huge heat energy consumption puts forward higher requirements for the industrial boiler equipment. Therefore, after careful consideration, Weifang Huabao Textile decided to introduce two sets of YQW series gas-fired thermal oil heater from ZOZEN Boiler, which helped the company successfully compete the "coal to gas" project, greatly reduce the energy consumption and further realize the green and sustainable development.
After a careful boiler market investigation in advance, Jiangsu Xinrui Aromatics finally chose to cooperate with ZOZEN Boiler with high-quality products and abundant project experience. According to the actual demands of aromatics production lines, ZOZEN Boiler designed the WNS series gas-fired and oil-fired steam boiler using two kinds of fuel that are natural gas and diesel for Jiangsu Xinrui Aromatics.
The WNS series three-pass condensing gas-fired steam boiler produced by ZOZEN Boiler not only can meet the actual demands of Nanjing Changli's honey production lines, but also can help the enterprise achieve the goal of saving energy, reducing emission and protecting the environment by virtue of its advantages of good performance in safety and efficiency and high degree of automation.
In order to meet the strict environmental protection requirements of Beijing city, ZOZEN designed WNS series gas-fired hot water boilers that used clean energy natural gas as fuel and adopted the advanced low NOx burner to ensure that NOx emission was lower than 50% and the flue gas was exhausted into the atmosphere via 15-meter chimney.
ZOZEN Boiler launched the oil-fired/gas-fired skid-mounted steam boiler in order to meet the demands from overseas market. The so-called skid-mounted boiler is to place all the boiler parts such as boiler proper, economizer, burner, valve & instrument, controlling cabinet, water treatment, economizer circulating pump, raw water pressure pump and so on together on one or two skid-mounted blocks to form a boiler system which can move orderly as a unit.
