The paper presents a model of a solid fuel boiler with the improvement of the locking mechanism to increase its efficiency, which in turn will increase the savings and ecological safety of such a boiler. The given calculation of the volume of dry gases, theoretical volume of nitrogen and the volume of water vapor, which makes it possible to determine the content of oxygen in the air and other elements in the fuel. Given a 3-d model of solid fuel boiler by means of FlowSimulation software. Based on the test results, the amount of combustion products leaving the chamber was shown. The research results show that, depending on the size of the boiler elements, there is no ventilation in the room where the boiler is located, and after an hour of operation, a long stay of a person may cause health problems. t has been shown that the excess air factor depends on the type of combustible fuel, the method of its combustion and the structure of the boiler combustion chamber. A construction of the closing mechanism of the combustion chamber of a solid fuel boiler is proposed. Based on experimental and computational research, a model of the boiler door handle was constructed, when automatic opening would be impossible. Such a design of the mechanism closing the combustion chamber of a solid fuel boiler allows to increase its efficiency as a result of the stability of the gas mixture composition and to reduce the risk of carbon monoxide falling into the room.
