(57) The invention relates to combustion equipment for combustible material, which combustion equipment includes a heating boiler (1) and a firebox in it (1.1). The combustion equipment also includes means for feeding the material to the heating boiler (1), and fans (4, 3) for feeding primary and secondary air to the heating boiler (1), in order to burn the material in the firebox (1.1). The equipment includes a briquetting machine (7.1) for forming the combustible material into briquets and a briquet-transfer pipe (7) connected to it, which is arranged to open into the firebox (1.1) thus forming a combustion zone. A larger blast pipe (8) arranged at a distance around the briquet-transfer pipe (7), for feeding primary air to the briquet.
