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.
With outstanding product quality and environmental protection performance, ZOZEN has occupied a certain market share in the dyeing and finishing industry and has obtained a good reputation. ZOZEN SZL series biomass-fired boiler is an environment-friendly boiler that is jointly developed by ZOZEN and Shanghai Jiaotong University. According to different characteristics of biomass fuels and different burning rates, ZOZEN rationally arranges the heating area of the furnace arch, furnace wall and furnace to ensure the combustion efficiency and design evaporation. Meanwhile, after numerous experiments, ZOZEN rationally arranges the primary and secondary air, which can effectively reduce NOx emissions and ensure the fuel is fully burned.
As a leading manufacturer of the industrial boiler industry, ZOZEN became the boiler supplier of Jinshan Mining with advantages of SZL series biomass-fired boilers in thermal efficiency and environmental protection. This series of boiler adopts double steam drums, and the combustion chamber is surrounded by membrane wall. Meanwhile, the boiler adopts a chain grate. Segmented wind bunkers and wind regulating devices are arranged on the lower part of the boiler to achieve precise air distribution and ensure full combustion of fuel. The thermal efficiency can reach over 88%, and all indicators have reached the international advanced level.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
Xinzheng Heli Thermal Co., Ltd. is a company specializing in heat energy production and central heating supplying, providing heat source for winter heating for people in Xinzheng . Facing the increasingly serious environmental problems, Xinzheng Heli decided to respond positively to the "coal to gas" policy, using clean energy natural gas as boiler fuel and introducing high efficient gas-fired boilers to replace the original coal-fired boilers. For this, Xinzheng Heli Thermal carried out an open bidding. After competitive bidding and strict selection,ZOZEN defeated other competitors and won the bid with its comprehensive corporate strength. The winning bid was ZOZEN energy saving and environmental protection product - SZS series condensing gas-fired superheated steam boiler (3 sets of SZS75-1.6-Q). The furnace and the front and rear walls of this series of boilers adopt membrane water wall structure, and the airtightness is good.
In the production process of chemical products, the refined processes including salt forming reaction, condensation reaction, desolventizing and drying have specific requirements for the temperature, hence, the boiler is an essential piece of equipment in chemical industry. Jiangsu Aolunda Technology Industrial Co., LTD. is a new high-tech enterprise specializing in developing and manufacturing functional fine chemical products that are exported overseas. All along, chemical enterprises are often heavy polluters. As a enterprise that has the courage to undertake the social responsibility, Jiansgsu Aolunda decided to upgrade the production line equipment to deal with the increasingly serious situation of environmental protection. As one of the important equipment of the production line, the boilers had to be replaced with more energy-saving and high efficient ones in an urgent need.
Jiangsu Aolunda had already heard about ZOZEN before and decided to conduct a field visit to ZOZEN in Yi
People cannot live a comfortable life without heating boilers in the winter, the normal and stable heat source is of great importance to human life. What is following is the increasingly serious problem of environmental pollution, implementing the policy of “coal to gas” is no time to delay, using gas-fired hot water boilers has been the general trend. Tianjin Jizhuangzi heat supply center is an enterprise specializing in city heat supply. In order to realize the “green heating”, the heat supply center decided to introduce a branch of gas-fired boilers to replace the old coal-fired boilers. ZOZEN successfully won the trust of Jizhuangzi heat supply center with its own strong comprehensive strength and rich experience in the heating industry. JIzhuangzi chose to cooperated with ZOZEN and ordered 3 sets of 58MW gas-fired hot water boilers (SZS58-1.6/130/70-Q) to provide heating source for citizens. This series of boilers adopts the design of " D " type membrane wall structure, the steam
