Reserves for Increasing the Energy Efficiency and Environmental Facility of Marine Boilers through the Application of Automation Tools

Abstract

Every year, more and more attention is paid to the problem of energy efficiency of ship power plants. Among the heat losses in a steam boiler, the largest are the losses with the output gases, which mainly determine its efficiency. Solving the problem of reducing these losses is an urgent task, which is the main goal of the work being performed. Its scientific novelty is the substantiation of the improvement of the automatic control system of the aggregated combustion device in order to reduce heat losses with the output gases. The work proposes to improve the algorithm of the control unit of the combustion device in order to ensure the fulfillment of the condition of the dependence of the volume of air injected into the combustion space during ventilation on the concentration of explosive gases dissolved in it. For the practical implementation of this solution, the use of a system of automatic control of the quality of the combustion process with signal transmission to the control unit of the combustion device is proposed. The proposed method of improving the operation algorithm of the combustion device control unit will minimize heat loss with the output gases Q₂ and will ensure a reduction in emissions of harmful substances into the environment.
