In 2016, the customer company invested in the construction of an annual output of 5,000 tons of electronic-grade high-activity copper oxide. The main raw and auxiliary materials are electrolytic copper, carbon dioxide and food-grade ammonium bicarbonate. The main processes include dissolution, pressure filtration, dehydration, static drying and so on. The company purchased steam boilers to provide necessary heat sources for the production process.
The boiler provided by ZOZEN Boiler adopts the double drums horizontal D type structure, belongs to the SZS series. The boiler applied full membrane wall in the front and rear of the boiler body, which effectively prolongs the service life of the boiler. Also, the membrane water cooling wall surrounding the combustion chamber ensures good air tightness, which improves the thermal efficiency of the boiler up to 98%.
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
