It is a boiler in which fuel to the combustion chamber is supplied manually through the hopper door. It uses the technique of bottom combustion of hard coal ensuring economical and clean fuel combustion.

To obtain optimal combustion conditions, regulation of the amount of incoming air is performed using the throttle of the lower doors, which regulation is manual or with the help of a draft gauge, throttle of the middle doors, as well as through secondary air throttles located on the side of the boiler. The boiler must be operated with a storage tank in order to meet the requirements of the PN-EN 303-5:2012 standard.

Advantages

Heat exchanger made of certified boiler plate
Primary fuel: hard coal
High combustion efficiency and heat exchange: above 89%
