Combustion system with dual combustion chambers for marine incinerator and control method thereof

Abstract

The invention discloses a combustion system with dual combustion chambers for a marine incinerator and a control method thereof. The combustion system comprises an incinerator, a second combustion chamber, an air blower, a draught fan, a combustor, a cyclone, a control unit, auxiliary control equipment, a temperature sensor, a pressure sensor, a second combustion chamber temperature sensor, an air outlet temperature sensor, a valve, a heat exchanger device and the like, wherein the second combustion chamber is a horizontal cyclone combustion chamber; swirl vanes and a dirty oil combustor are arranged inside the second combustion chamber; the second combustion chamber is used for performing secondary combustion on flue gas which is not combusted fully; the flue gas outlet of the second combustion chamber is connected with the heat exchanger, and primary and secondary air are heated by using residual heat of flue gas; the flue gas outlet of the second combustion chamber is communicated with the atmospheric air through the draught fan; and a ventilation branch is formed at a tail flue gas outlet, and is connected with primary and secondary air pipelines to prevent the exhaust gas temperature from getting too high. According to the control method, various possible conditions occurring in the working condition of the incinerator are considered comprehensively, so that the combustion efficiency is increased, efficient and stable running of the marine incinerator is realized, and the pollutant emission is reduced effectively.

Description

technical field [0001] The invention relates to an incinerator, in particular to a double combustion chamber marine incinerator combustion system and a control method thereof. Background technique [0002] Ocean-going ships generate a lot of garbage during the transportation of goods. In order to dispose of combustible waste on board, most ocean-going ships are equipped with incinerators as waste disposal equipment. The incineration of ship garbage can reduce the capacity greatly, improve the effective utilization rate of the hull space, improve the sanitary environment, and the residue after burning has little impact on the environment. The structure of the marine incinerator has a direct impact on the combustion effect of the garbage, and the level of its organization and combustion has a great influence on whether the garbage can be fully burned and the emission of pollutants can be reduced. [0003] The existing intermittent feeding marine incinerator generally adopts ...
