As the determination of country to prevent and control air pollution is increasing, various policies have been introduced across the country. Almost every region, the timeline and number of boiler renovations have been issued. In order to maximize the cost savings of the company’s operations, most companies will choose to convert coal-fired boilers to gas-fired boilers, and the rubber chemicals industry is no exception. With the increasingly stringent policies and regulations being promulgated in succession, in 2013, Huasheng Rubber planned rubber auxiliary energy-saving renovation project, they purchased a 10 tph WNS condensing gas-fired steam boiler at ZOZEN boiler. The condensing boiler is a hull-type three-passes pyrotechnic tube structure researched and developed based on the mature technology of the current gas boiler, the heat load of the boiler is low. An additional condenser is installed at the tail of the flue to increase the boiler inlet temperature and reduce the temperature of the flue gas. The thermal efficiency of the boiler is as high as 98%. The boiler uses natural gas as fuel, which has a relatively low level of atmospheric pollution, and in compliance with the country's rigid standards, the boiler's pollutant discharge can reach a minimum of 30 milligrams per cubic meter, and emissions to the atmosphere are even lower.
ZOZEN boiler are equipped with an intelligent system as standard and provide all-round power failure protection, water level monitoring, and automatic adjustment of temperature and steam pressure for the boiler. Once the boiler is abnormally operating, the boiler will initiate safety protection measures to ensure the safety of the boiler room and staff. The fuel is fully burned, which improves the thermal efficiency and reduces the operating cost of the boiler.
