The invention discloses an oxygen supply and thermal insulation device and a flammable gas combustion chamber with the same. After being inlaid in an inlet of the combustion chamber, the oxygen supply and thermal insulation device connects an inner cavity of the combustion chamber with a flame jetting opening of a combustion device. The oxygen supply and thermal insulation device comprises a gas inlet cylinder formed by mutually nesting an inner cylinder and an outer cylinder. An oxygen supply pipe is inserted between the inner cylinder and the outer cylinder, and the space between the inner cylinder and the outer cylinder is filled with temperature-resistant castable. The inner cylinder, the outer cylinder and the oxygen supply pipe are mutually fixed through supporting rings. A pipe cap used for adjusting the gas inflow of the combustion chamber is installed at the gas inlet end of the oxygen supply pipe. According to the oxygen supply and thermal insulation device and the flammable gas combustion chamber with the same, flammable gas can be fully burnt, and the burning temperature can be above 1000 DEG C, so that energy in the flammable gas can be fully used. Through a special sealing structure at the inlet of the combustion chamber, heat loss is avoided, so that heat energy generated by burning the flammable gas is used furthest. In addition, the inlet of the combustion chamber is welded in a sealed mode through a hubbed flange structure, so that the functions that the service life of the combustion chamber, the gas inlet cylinder and other parts is prolonged are achieved.
