Abstract
Cooking boilers powered by natural gas are promising equipment for the preparation of feed in private farms. Based on the patent search, it has been established that there is a wide choice of gas-using boilers with different levels of automation of the process of thermal processing of the product and ensuring safety during operation. At the preliminary stage of the study, it was found that with a smooth control of the power of the gas burner of the digester during the preparation of feed, gas savings of up to 19% are achieved. The principle of self-regulation of gas consumption by a gas burner is determined in proportion to the heat flow consumed by the digester. A working experimental sample was made on the basis of an automation kit for a digester with smooth control of the power of a gas burner. A mathematical model has been developed that describes the processes of heat and mass transfer in a feed boiler with self-regulation of power. Based on the analysis of energy supply systems in digesters and heating boilers, the expediency of developing a new promising power self-regulation scheme based on Peltier semiconductor thermoelements has been established. As shown by the results of experimental studies of automation in various operating modes, the voltage on thermoelectric elements changes in proportion to the temperature difference. It is established that the minimum voltage is 0.07V, the maximum is 0.7V. The voltage and temperature of the product and hot steam in the jacket were measured using TEK DT 830B multimeters. It has been established that the best sensitivity of the thermal regime control system is achieved if the thermoelectric converter module is equipped with nine elements that change the output voltage in proportion to the temperature difference in the steam jacket of the digester.
