Abstract

An efficient coal-fired boiler is provided. A jacket (1) with a cylindrical outer-wall and a sting-bead-like inner wall is internally provided with a string-bead-like chamber (2) corresponding to beadlike inner wall; the jacket (1) is communicated with the string-bead-like chamber (2) by a conduit (3). A cavity between the jacket (1) and the string-bead-like chamber (2) constitutes a hearth and a flue. An ash hole (4), a mouth (5), an inlet (6), an ash removal hole of the flue (7) and a draining port of the jacket (8) are arranged on side wall of the jacket (1). A stack nozzle (9) and an outlet (10) are arranged at the top of the jacket (1), and a grate (11) is arranged at the under-part of the jacket (1). The utility model has the advantage of high thermal efficiency.
