Is intended for heating water and can be used in the systems of centralized heating, hot water supply for industrial and household purposes and for technological purposes in fuel-bed firing of hard fuel.

The furnace is operating according to the principle of continuous casting of fuel upon the burning layer, and that in a combination with a slow return movement of a chain tape grid provides the bottom ignition over the whole area of the grating and stable burning. A furnace’s special feature is the combination of mechanical, being the basic one, and of pneumatic casting of fuel allowing to optimize the burning of dust fractions in the furnace’s bulk. The design of the furnace allows to automate the process of burning.

The boiler is delivered fully immurated and in boarding, is completed with devices of control and safety, fixtures, fan, dust catcher and smoke exhauster.
