The invention discloses a combustion boiler with good shock absorption and noise reduction performances. The combustion boiler comprises a shock absorption base and a heating box, grooves being distributed equidistantly are formed in the inner wall of the bottom of the shock absorption base, and the inner walls of the grooves are provided with shock absorption springs in a welded manner. The outerwall of one side of the shock absorption base is provided with a fixed block in a welded manner. Fixed pieces being distributed equidistantly are fixedly arranged on the inner wall of one side of theheating box through bolts, and a water delivery pipe being placed obliquely is fixedly arranged on the inner wall of one side of each fixed piece through another bolt. The water delivery pipes are distributed on the inner wall of one side of the heating box in a snake shape, and air holes are formed in the snake-shaped bending places of the water delivery pipes. When water flow is agitated in thewater delivery pipes to generate lots of bubbles and shock, the shock absorption springs enable the shock to be substantially reduced. Thus, the shock absorption ability of the combustion boiler is increased, and the stability of the combustion boiler is improved. The water flow speed is decreased when the water flow moves in the water delivery pipe, so that the bubbles generated during agitatingare few and can be discharged from the air holes, and the generation of shock and noise is reduced.
