Boiler for burning straw in bales - cubes

The Q PLUS AGRO straw burning boiler is a medium capacity boiler. It is designed for burning straw bales. The boiler is equipped with HT tronic 251 control unit with an additional flue gas temperature sensor and buffer pump control.

Appropriate aeration of the combustion chamber using secondary air ensures effective combustion of fast-gasifying straw while maintaining appropriate combustion parameters. The use of modulating blower fans makes it easy to control the combustion quality.

Naturally, a heat buffer of approx. 2 m3 for each 50 kW of boiler capacity must be used in every heating system with a straw-fired boiler. The selection of the size of the heat buffer capacity should be made by the installation company in consultation with the planner.

The boiler is equipped with HT-tronic 251 control unit adapted for AGRO boiler with additional flue gas sensor and outputs for buffer pump and central heating circulation pump.
