I’m seeking advice from experts: what are the differences between the 20-ton coal-fired chain steam boiler produced by Zhengzhou Boiler Factory and the 20-ton coal-fired chain steam boiler produced by Wuxi Xinen Boiler Factory?

There are 2 types of common 20-ton coal-fired chain steam boilers. Upper and lower 2-piece assembly type, along with 3 upper pieces and a boiler base. Are there any differences between these two types of chain boilers?
