1. Accumulating hopper for solid fuel and solid loose materials comprising a sloping vertical wall placed at the bottom of the bunker an outlet for discharging material from the hopper, thus preventing buildup of material on the wall of the hopper, bridging material moving mechanisms are used, the mobile environment, pulses within the hopper and the material, characterized in that the rotating part of the hopper has a cylindrical shape rotates about a horizontal or inclined axis at an angle less than 35 °, the rear part of the rotating part of the hopper is located axially inside the fixed part of the hopper having a bottom discharge hatch rotating the hopper has a hatch discharge periodically while turning 360 ° coincides with the hatch unloading the fixed part of the hopper, the rotating part of the hopper mounted on the front and rear bearing, the front bearing supports the rotating part of the hopper on the outer perimeter of the back support is connected to the rotating part of the hopper on an axis rotation, the fixed part of the hopper mounted on the back support, the geared motor for driving a rotating part of the hopper, the internal screw feeder surface is fixed on the inner perimeter of the rotating part of the hopper, the inner screw feed surface fixed blades, rippers, set at an angle to the inner helical screw axis feeding surface, the sides of the hopper unloading hatch movable annular impingement limited, fixed on the perimeter of the inner part of the fixed part of the hopper on the size and length of unloading hatch horiz
