industrial boiler

The new VII water-fire tube steam (VI hot water) boiler is a new eco-friendly and energy-saving product co-developed by our company and Professor Li Zhiguang—a famous boiler expert, professor of Harbin Institute of Technology and director of Beijing Institute of Light Boiler after 30 years of study and experiments, adapting to the conditions of our country. It is called as a revolution of industrial boilers by domestic and foreign experts. Its main characteristics are as follows:

With efficient diabatic spirally corrugated tube, it is designed by using heat transfer and flow resistance technologies of Harbin Institute of Technology. The boiler's actual capacity is 10-15% higher than name plate capacity: As the physical dimension and smoke speed of the spirally corrugated tube are rational, and the spirally corrugated tube doesn't form soot or wear when the boiler normally operates, the boiler's capacity and heat efficiency don't reduce with the extension of operating time;

The main heating surface is installed in the shell, so it doesn't leak cold air to the smoke side, and nearly a half of shell surface is heated. The boiler’s heating up time is one third shorter than other furnaces, and heat efficiency is the highest in various furnaces;
