KWMS boiler

KWMS heating boiler is a new generation solid fuel boiler. Combustion process is stimulated by an induced air flow delivered by blowing ventilator which is controlled by microprocessor. Combustion process occurs vertically (so called upper-combustion process). As a result of high temperature carbonization effect takes place. The remained gas is then after-burned in secondary air flow which is delivered to various levels of the combustion chamber by multiple point air jet system. KWGR boiler is produced in multiple variants as per order. Caution! Boiler does not need a chimney insert.

Base for appropriate boiler selection is a thermal balance of the heated area created according to thermal standards for buildings. The nominal thermal efficiency should equal or be little higher (about 10%) than calculated heat requirement of the heated area. In chart nr 2, No. 4 are information about size of area that can be heated by KWMS boilers. Given data is approximate and is specified for rooms of 3m height.

KWMS heating boilers have certification of compliance with energy efficiency criterion.

Emission and energy tests were conducted by:

Institute of Heating and Sanitary Technology in £ód¼.
Institute for Chemical Processing of Coal in Zabrze.

KWMS heating boilers are designed to heat water in the central heating systems to the temperature not exceeding 900 °C at the boiler’s outlet. KWMS heating boilers are designed for heating living quarters, warehouses, commercial halls, workshops, farm buildings, glasshouses, schools etc. They are used in the central heating system and central hot water systems (gravitational or induced systems).
