The purpose of the article is to assess development of the temperature field of the bases for foundations of horizontal burner devices (HBDs), considering seasonal changes in temperature and operation of horizontal flares (HFs). Predictive analysis is based on the solution of a quasilinear system of thermoelasticity equations, which takes into account the mutual influence of mechanical and temperature fields. An iterative algorithm is proposed that allows, at each time step, to obtain separately the solution of the heat conduction and elasticity equations while maintaining their physical coupling. The results of thermal insulation calculation of a flare pit for a gas well cluster are presented.
