The invention discloses a combustion boiler convenient to move and install. The combustion boiler comprises a boiler body. Two universal wheels are fixedly arranged at the bottom of the boiler body. Acontaining groove is formed in the bottom of the boiler body and located between the two universal wheels. A both-way threaded rod is movably arranged on the inner side of the containing groove. Oneend of the both-way threaded rod penetrates through the boiler body and extends to the outer side of the boiler body. The surface of the part, on the inner side of the containing groove, of the both-way threaded rod is provided with two sliding blocks in a threaded manner. Supporting columns are movably arranged at the bottoms of the sliding blocks, and the bottoms of the two supporting columns are movably provided with a base. A both-way motor drives the both-way threaded rod to rotate, the sliding blocks are made to move on the surface of the both-way threaded rod, the supporting columns aredriven to move, accordingly, the base is made to ascend and descend, moving and supporting of the boiler body are convenient, and practicability of the device is improved.
