Product Description

Product features
1. The boiler adopts double drum, monolayer arrangement, compact structure, as well as large heating surfaces which are 10% more than those of same kinds of products, featuring the following advantages such as sufficient output, safe and reliable operation, short construction period, and low installation cost ect.

2. The design of cyclone reburning chamber in furnace decreases dust contained in the flue gas. At the same time, incandescent carbon black particles burns further, enhancing the boiler thermal efficiency, and decreasing gas blackness, as a result, the gas emission concentration meets the requirements of grade A environmental protection area.

3. The grate employs the technology patent of small roller structure, boundary grate and so on, improving the operation reliability of the boiler.

4. Since the adoption of technology patent for the sealed wind chamber and bilateral grate air register, and the application of machining cone seal structure to grate adjusting air eauipment, the sensitivity of the grate is duely improved.

5. Other energy saving equipments are optional according to the customers' requirements.
