The combustion chamber of lower two open ends, in the vertical direction in two layers adjacent of shield, the radial width of upper one layer of shield is greater than
Next layer of radial width, so that an injection area communicated with combustion chamber fluid is formed between adjacent two layers shield, every layer
Shield lower end is equipped with the cooling duct entrance；Several injection burners, every layer of shield are equipped in the injection area
Including the cooling jacket for forming the chamber wall cylinder of the combustion chamber and being arranged in outside the chamber wall cylinder, every layer of shield
The cooling jacket be tightly connected with the chamber wall cylinder in upper lower edge position, the cooling jacket and the combustion chamber
Coolant flow channel is formed between wall cylinder, forms the ventilation knot being connected to the combustion chamber and coolant flow channel on the chamber wall cylinder
Structure, the cooling jacket bottom end are equipped with the ring pipe being connected to the coolant flow channel, and the cooling duct entrance is arranged described
On ring pipe, the chamber wall cylinder includes the compound wall cylinder being arranged in a vertical direction, in the vertical direction adjacent two layers of walls
In cylinder, the radial width of upper one layer of wall cylinder is greater than next layer of radial width so that formed between adjacent two layers wall cylinder one with
The gap that the combustion chamber and coolant flow channel are in fluid communication, the ventilation device includes the waveform piece being arranged in the gap
Shape structure, the waveform laminated structure forms several cooling airways, including the first cooling airway and the second cooling airway, described
First cooling airway includes cooling airway of the wave opening towards upper layer wall cylinder, and second cooling airway includes wave opening court
To the cooling airway of lower layer's wall cylinder.
