Heat generators producing hot fuel mixture combustion products for further heat treatment of different materials by these products are widely used in various industries. They are used, for example, in the operation of drying plants, disposal of hazardous waste, and production of building materials. Currently, there is a need to create mobile heat and gas generators suitable for transportation and rapid deployment in the field. The purpose of the work carried out in BMSTU was the development of all-metal heat and gas generators for use in drying units. In the course of the development the accumulated experience in working out the combustion chambers of rocket and air-jet engines was realized. Methodology was developed to calculate distribution of key parameters of working process occurring in the combustion chamber of the mobile heat generator on the fuel components of the air–natural gas: optimal scheme of mixing was selected by numerical simulation, the calculated fields of combustion product temperatures and concentrations of fuel components in combustion chamber volume were obtained. To implement practically the working process and to confirm the correctness of the calculations a heat and gas generator was designed and experimentally tested. Comparison of calculated and experimental data showed satisfactory agreement of the results.
