Product Description

Product Description
Industrial chain grate coal fired steam boiler
The DZL series quickly installed coal fired steam boiler is the most advanced water-fire tube boiler in Chinese market, This series boiler can be used in textile, food and package factory with high efficiency, small in size and long working life.

The coal fired steam boiler after improvement takes use of structure of wing type smoke duct, one-way screwed smoke tube, arched tube plate, smoke and gas separate room and several other advanced technology, which has increased the water circulation speed and safety factor. This boiler series is well designed, compactly made up, quickly installed, mono layer, so that the civil engineering and investment could be saved. With these improvement, the boiler's working life extend much to be the national energy saving product.

1-6 T steam boiler usally transported as entiraty part, Capacity more than 8t(including 8 t/h)are transported as up body and bottom body (chain grate) .
