LABORATORY APPARATUS Russian patent published in 2019 - IPC G09B23/16 

FIELD: physics.

SUBSTANCE: invention relates to installations for conducting training sessions on the following disciplines: "Technosphere safety", "Technological processes and polluting emissions", "Industrial ecology", "Environmental protection in heat engineering", and allows to detect influence of flow rate, temperature and humidity of air supplied to combustion chamber on composition of combustion products. To achieve the technical result, a laboratory plant is proposed, which contains a heat-insulated vertically installed tubular housing (1), in which there is electric heater (5) and humidifier (9), above each of which there are flow mixers (8) and thermocouples are installed to control temperature of the air flow. An electric heater is connected to autotransformer (6) and wattmeter (7) for controlling and measuring power, and the humidifier is connected to water tank (10) with tap (11) and a water collection container (12). According to the invention, the laboratory installation additionally contains combustion chamber (2) with crucible (17) for solid fuel charge. Combustion chamber (2) is equipped with external heat insulation (13), inlet (14) and outlet (15) branch pipes and is connected to housing (1) by means of coupling joint (18) with sealant. Tubular housing (1) is made in the form of a glass tube with two constrictions (8), which are flow mixers located above electric heater (5) and above humidifier (9), and with a bent outlet section connected to the inlet branch pipe (14) of chamber combustion (2). Besides, housing (1) additionally comprises in inlet branch valve (4) for control of air flow rate supplied to installation, and in outlet branch pipe (15) of combustion chamber there installed is thermocouple for measurement of temperature of outgoing gases.

EFFECT: technical result consists in improvement of efficiency of laboratory installation and expansion of scope of analysed processes.
