The invention discloses an industrial steam furnace with the high heat energy using rate. The industrial steam furnace comprises a water tank and a furnace body, the water tank is arranged on the furnace body, the inner side of the water tank is provided with a burning zone, a main heating zone is arranged on the inner side of the furnace body, and a plurality of smoke discharge pipes are arranged at the middle position of the top of the water tank; a circulating pipe is arranged on the right side of the water tank, a circulating pump is arranged on the circulating pipe, and a plurality of sets of communication pipes are evenly arranged in the burning zone on the inner side of the water tank from top to bottom; a plurality of heat conduction plates are further arranged at the middle portions of the communication pipes, transverse separating plates are arranged at the positions, on the lower sides of the communication pipes, in the water tank, and water via holes are formed in the middle portions of the left side and the right side of each transverse separating plate in a longitudinally-staggered manner; and vertical separating plates are arranged at the positions, on the middle portions of the front side and the back side of the water tank, between every two adjacent transverse separating plates. The industrial steam furnace solves the problems that in the prior art, the heat energy using rate is low, and the water heating uniformity is poor are solved.
