20 t/h chain grate boiler is the main burning equipment in ZG Boiler’s industrial combustion devices and most widely used. Heating surface of this kind of boiler made by ZG Boiler is appropriately arrangement and full. So,the boiler has sufficient output and high efficiency. Main types of these boilers are as follows:
1, DZL leaning drum package boiler ,1t/h~4t/h
2, shop-assembled boiler, 6t/h~20t/h
3, semi-assembled boiler, 20t/h~20t/h
4, field-assembled boiler,10t/h~75t/h
5, large scale heat water boiler, 29MW~70MW
ZG 20 t/h Biomass Fired Chain Grate Boilers Advantages
20 t/h chain grate boiler with two wings flue series boiler is small size but output is big. And pressure rises faster with higher thermal efficiency, which is domestic initiative. And the boilers are the national mechanical and electrical energy-saving products with national patent.
1. New furnace structure avoids to produce bulge defects which happens because of direct heating the bottom of the drum.
2. Avoid flue tube plate crack
3. New arch design for inferior coal combustion and coal adaptability
4. Independent adjustable wind chamber under the fire grate, and wind comes from two sides. Ventilated section ratio reaches 100% , and can be adjusted flexibly and air flows evenly.
5.Push-pull type damper ash removal device effectively prevents deformation of the secondary combustion and grate air leakage.
