Abstract

A smokeless incinerator burns unburned gas to inhibit generation of black smoke. The incinerator contains a first combustion chamber with a main combustor having firebrick walls into which waste is thrown and an auxiliary burner for burning the waste. A water cooling jacket is located above the main combustor. A second combustion chamber is located on top of the first combustion chamber and has a re-burning burner for unburned gas. A filter-equipped combustion chamber is aligned with and adjacent the second combustion chamber and has a ceramic filter. A third combustion chamber is aligned with and adjacent to the filter-equipped combustion chamber and has a dust collection cyclone. A fourth combustion chamber is located on top of the third combustion chamber and has a re-burning burner for unburned gas. An exhaust stack is located on top of the fourth combustion chamber and has a forced exhaust.

Abstract

[Problem] To provide a smokeless incinerator that can suppress generation of black smoke by completely combusting uncombusted gases and that does not have the risk of damaging a burner in a combustion chamber even when combustion is sufficiently performed. [Solution] The present invention includes: a primary combustion chamber A comprising a main combustion section A1 in which an object to be combusted is placed and that includes a refractory brick wall A12 and a combustion assistance burner A31 for assisting combustion, and a water-cooling jacket section A2 that is disposed on the refractory brick section A1 and that includes a water-cooling jacket wall A27; a secondary combustion chamber B that is disposed above the primary combustion chamber A and that includes a re-combustion burner B1; a tertiary combustion chamber D that includes a dust-collecting cyclone D3 and a combustion chamber C having a filter, which are sequentially aligned on a single line on the side of the secondary combustion chamber B; a quaternary combustion chamber E that is disposed above the tertiary combustion chamber D and that includes a re-combustion burner E1; and an exhaust pipe F that includes forceful exhaust means F2 and F5.
