The object of the invention is a method of drying fibrous biomass in ballots and a device for realizing the process according to this method, while the ballots are designed to be bunt in a boiler. A method of drying fibrous biomass formed into ballots, consisting in pumping a drying medium in the form of flue gases, is characterised in that the raw flue gases are pumped through a ballot, while the flue gases are supplied to a ballot through a pipe (13) with a large diameter that exceeds 300 mm and the dried-up ballot is passed directly over to a combustion chamber. The drying process is realized in an enclosed chamber (3), located by a boiler (16) for burning straw. A device for drying fibrous biomass formed into ballots that consists of a chamber that contains a flue gas inlet is characterised in that the flue gas inlet ends with a pipe (13) of large diameter that exceeds 300 mm and the pipe is fitted with a movable end part (14), while there is a ballot feeding screw (5) in the chamber (3) and it is equipped with a pushing frame (11) that encloses the end part (14) of the pipe (13) that supplies flue gases. The end part (14) of the flue-gas-feeding pipe (13) has got a flange located near the back end and it is joined to the flue-gas-feeding pipe with a spring (15).

Abrégé

The object of invention is a water boiler fired with straw in the form of compressed bales, which can be used in heating systems, both for individual residential buildings and for whole housing estates. The water boiler fired with straw, according to the invention, is composed of a straw combustion chamber (1 ) and a gas combustion chamber, located side by side and surrounded by a jacket, and the two chambers are separated from each other with a partition that has an opening at the bottom, and there is a heat exchanger (3) above the chambers. The boiler is characterized in that the straw combustion chamber (1) has a wall made of steel pipes (4) that are vertically aligned filled with water, and the steel pipes (4) are connected to horizontal collecting pipes (5, 6) at the top and at the bottom. The vertical pipes (4) filled with water are fixed to each other with steel ribs (7).
