Abstract

The invention discloses a control method of a marine incinerator, which belongs to the field of combustion technology, shipboard automation technology and environment technology. The control method is applicable to three combustion modes, namely, solid waste combustion, sump oil combustion, and solid waste combustion and sump oil combustion, is simple and easy to be realized, and utilizes sensor technology and programmable control technology to control the whole working process of the incinerator. Considering the working parameter of the marine incinerator under various working condition completely, the automation, high efficiency, stabilization and reliable operation of the marine incinerator can be realized on the basis of accuracy control of the incinerator hearth temperature, hearth pressure and releasing temperature of flue gases. The invention completes the influence of continuous changing of various parameters to the whole combustion process during the spraying burning process, leads the waste and sump oil to be burnt fully, improves the burning efficiency, and reduces the dusty gas emission greatly.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for a marine incinerator, which belongs to the fields of incineration technology, ship automation technology and environment technology. Background technique [0002] According to the national standard GB10836-89 technical conditions for marine incinerators and the relevant regulations of the International Maritime Organization MARPOL73 / 78 Convention, marine incinerators are mainly used to incinerate solid wastes that are similar to household wastes and liquid wastes generated during ship operations, such as Domestic waste, waste accompanying freight, waste generated during maintenance and operation, freight residues and fishing tools, etc., the incinerator should strictly follow the relevant standards during the working process, the maximum temperature at the outlet of the combustion chamber is 1200 °C, and the exhaust gas discharge The maximum temperature shall not be higher...
