Claims (5)

1. Device for the continuous use of heat from solid biogenic fuels compacted into bales, namely straw and stem-shaped energy plants, such as straw, reeds, hay, peat or the like in combustion plants of low output (up to approx. 100 kW) with discontinuous fuel feed without prior comminution and briquetting the same for the continuous provision of the heat generated, the method being carried out in two stages and the gasification in a first stage and the combustion in a second stage, characterized in that the combustion system comprises the following features, namely:
  • - an insulated housing ( 4 ) (preferably container) in which all process-specific functional modules are arranged,
  • - a gasification chamber ( 1 ) with a vertically oriented longitudinal axis,
  • - That the cross section of the gasification chamber ( 1 ) is adapted to the fuel bale ( 6 ) in a form-fitting manner,
  • - That in the absence of adaptation of the gasification chamber ( 1 ) a bell-like cover ( 20 ) adapted to the fuel bale ( 6 ) is inserted in the gasification chamber ( 1 ),
  • - That the covering hood ( 20 ) carries extraction bores ( 22 ) or slots ( 21 ) at the lower edge,
  • - That the covering hood ( 20 ) is supported on supports ( 23 ) with respect to the ash grate ( 5 ),
  • - An ashtray ( 5 ) in the lower part of the gasification chamber ( 1 ), which is designed as a hedgehog or stilt grate,
  • - That the ash grate ( 5 ) comprises an adjustable and pivotable grate base plate ( 5.2 ),
  • - That the grate base plate ( 5.2 ) carries hollow lance-like stilts ( 5.3 ) as hedgehog or stilts grids, which are closed on one side upwards,
  • - that the closure of the stilts is flat, round, conical, flattened and pointed or cruciform pointed,
  • - that the grate base plate ( 5.2 ) is fixed at an incline,
  • - that the grate base plate ( 5.2 ) is pivotably articulated in a joint ( 5.21 ),
  • - that the grate base plate ( 5.2 ) is supported on its joint-free side on a fixed or adjustable abutment ( 5.22 ),
  • - that the stilts ( 5.3 ) are fitted vertically in the grate base plate ( 5.2 ),
  • - that the stilts ( 5.3 ) below the grate base plate ( 5.2 ) are open and have air passage holes ( 7.2 ) on the gas chamber side,
  • - that a diverse number of nozzle bores ( 7.1 ) are arranged in the grate base plate ( 5.2 ) between the stilts ( 5.3 ),
  • - That on a long side of the gasification chamber ( 1 ) a door ( 11 ) extending over the entire chamber height is pivotally arranged,
  • an ash chamber ( 5.1 ) associated with the ash grate ( 5 ) with a cleaning door ( 5.11 ),
  • - a primary air supply ( 7 ) below and / or above the grate base plate ( 5.2 ),
  • - A switchable flue gas recirculation line ( 17 ) to the gasification chamber ( 1 ),
  • - an observation and ignition hole ( 18 ) in the gasification chamber ( 1 ),
  • - A vertically aligned and parallel to the gasification chamber ( 1 ) arranged two-pass combustion chamber ( 2 ), consisting of a mixing and pre-combustion chamber ( 12 ) and an afterburning chamber ( 13 ),
  • - a secondary air supply line ( 8 ) in the upper region of the mixing and pre-combustion chamber ( 12 ) and a fuel gas inlet ( 10 ) from the gasification chamber ( 1 ),
  • - A flow chamber ( 14 ) designed as a calming and deflection zone between the mixing and pre-combustion chamber ( 12 ) and the afterburning chamber ( 13 ),
  • - That the diameter, cross section or the chamber length of the afterburning chamber ( 13 ) is greater than that of the mixing and pre-combustion chamber ( 12 ),
  • - a heat exchanger ( 3 ), preferably with two vertically arranged trains ( 3.1 , 3.2 ) and a deflection chamber ( 15 ) arranged between them,
  • - a suction and / or pressure blower ( 9 ) behind the heat exchanger ( 3 ) in the flue gas outlet ( 19 ) or in the primary and secondary air supply line ( 7 ; 8 ),
  • - a heat store as a buffer store in parallel or series connection to the heat exchanger ( 3 ),
  • - a temperature sensor T 1 directly above the ashtray ( 5 ),
  • - a temperature sensor and λ probe TS 1 and TS 2 at the inlet and outlet of the combustion chamber ( 2 ),

  • - That the sensors T 1 , T 2 , TS 1 and TS 2 are computer-aided with control elements in the primary and secondary air line ( 7 ; 8 ).
2. Device according to claim 1, characterized in that the gasification chamber ( 1 ), the combustion chamber ( 2 ) and the heat exchanger ( 3 ) are arranged in parallel one behind the other.
3. Device according to claim 1, characterized in that the combustion chamber ( 2 ) and the heat exchanger ( 3 ) are arranged side by side behind the gasification chamber ( 1 ),
4. The device according to claim 1, characterized in that the combustion chamber ( 2 ) is arranged directly above the heat exchanger ( 3 ).
5. The device according to claim 1, characterized in that the heat accumulator in Container or stationed separately.
