Product Discription
Series Double Drum Chain Grate Biomass Water Boiler
The biomass hot water boiler From the drum chain of SZL, The main engine of the Caldeira is designed As a longitudinal arrangement of two drums, The upper barrel is equipped with a steam water separation device, The lower barrel is equipped with an exhaust manifold device The During the established period, and the left and right sides of the furnace are equipped with water wall tubes.The Light Current grid is used to automatically add fuel, and the back of the grid is a reprimand chamber and convection pipe. Ade is a economizer or an air preheater. The induced drafts fan and fan ar e distributed for mechanical ventilation, and an automatic gutter discharge is equipped. The fuel falls into the Current grid and enters the combustion furnace. It enters the flow of the tail through the furnace, forward chamber, convection tube, economizer or pre -heater, enters the powder collector, the induced fan, and finally discharges into the atmosphere
Product Features
1. simple installation:
Boilers are generally quick loading devices that are convenient for transport and site installation, significantly shorten the construction cycle, save installation costs, and allow boilers to start on time.
2. Reliable action:
The boiler heating surface is reasonably positioned, the water circulation is smooth and the heating surfaces are cooled in time to ensure the safe operation of the boiler.
3. simple maintenance:
The boiler drum is equipped with maintenance holes so that it can be repaired. It is convenient to open the smokebox in front of the oven, convenient and clear for staff inspection, which provides good conditions for proper processing.
4. Complete combustion:
Using secondary air and a sensible kiln design, the fuel can be completely combusted and the black smoke can be removed.
5. High efficiency grate:
The boiler grate employs two -way ventilation and dedusting techniques which naturally make the front end of the grate ventilable, prevent air leakage, oil leakage and irregular ventilation, and is easy to use. Compared to a normal grate, it has obvious advantages.
6. Removing comfortable ash:
The boiler may be equipped with multiple ash removal holes capable of removing the ash in a timely and effective manner, avoiding malfunction caused by accumulation of cauldron ash and reducing thermal efficiency, and ensuring stability of cauldron load.
