ZOZEN boilers for the chemical industry



Current situation of chemical industry

The chemical industry is an indispensable part of the national economy. However, in most chemical companies, due to outdated equipment and backward processes, the waste heat generated in production are not well recycled, resulting in high energy consumption. With the increasingly strict environmental protection policies, some companies are forced to limit or stop production. The introduction of advanced production processes and equipment is the transformation direction of each chemical company.



Energy-saving boilers for chemical industry

The boiler is the important and frequently usedequipment in the chemical industry, which provides sufficient heat source and power source for the chemical industry's distillation, evaporation, polymerization, condensation/deemulsification, lipidation, drying and other production processes. The boiler is also the main energy-consuming equipment in the production process. The use of energy-saving boilers has a significant impact on reducing the cost of the enterprise.



Gas-fired steam boiler

ZOZEN gas-fired steam boiler adopts a large-volume furnace to ensure sufficient fuel combustion, and it has sufficient steam storage space and heating area to efficiently generate high thermal energy and high quality steam. Meanwhile, the energy saving and environmental protection effects of the boiler are remarkable, and the emission of NOx is ultra low.
