The invention belongs to the technical field of
combustion furnaces, and particularly relates to a reciprocating grate-fired furnace. The reciprocating grate-fired furnace comprises a furnace body, a
coal hopper, a front arch, a rear arch and a grate, wherein a boiler
barrel is arranged on the upper portion of the interior of the furnace body, a
combustion chamber is arranged on the lower portion of the interior of the furnace body, and a
flue is formed between the boiler
barrel and the
combustion chamber; an opening is formed in the inner wall of the side, with the
combustion chamber, of the furnace body, and the
coal hopper is arranged outside the opening; the front arch, the rear arch and the grate are arranged in the
combustion chamber, the front arch is arranged above the opening, one end of the rear arch is installed on the inner wall of the other side of the furnace body, the other end of the rear arch is a free end and is arranged between the opening and the front arch, and a gap is reserved between the free end and the inner wall on one side of the furnace body; the grate is installed at the bottom of the furnace body, and the
coal inlet end of the grate penetrates out of the opening and is arranged below the coal hopper. According to the reciprocating grate-fired furnace,
anthracite serves as fuel of the reciprocating grate-fired furnace instead of secondary soft coal, the purposes of energy saving, emission reduction and consumption reduction are achieved, and the production cost can be reduced to a large extent.
