Horizontal internal combustion steam, coal chain grate boiler
1. Signle durm design
2. Boiler capacity of 1-35T/H
1. Features of Coal Fired Steam Boilers:
1). This thread boiler smoke pipe, arch tube sheet, wing flue structure, is the first victory in national development and National patent in 1991, after nearly two decades of continuous improvement and perfection of its structure is more reasonable, environmentally friendly energy. Effects become more prominent.
2). For the application of different fuels, chain grate and reciprocating grate is divided into two series. With energy, strong radiation arch, can be applied to all types of bituminous coal combustion.
3). With high standards, high-quality auxiliary equipment, accessories, automated control to ensure the boiler is safe, stable.
4). Compact, 1-10T / H fast assembly, 15-35T / H large assembly, single-layer arrangement, one-time investment province.
5). Boiler capacity of 1-35T / H (0.7-29MW).
2. Advantages of our production and service
1), 100%safety, running stably, excellent water level and pressure control, fully automatic operation
