A nonstationary model of gas combustion in a porous cylindrical heat generator with allowance for heat losses inside the body and from the outer surface is proposed and numerically analyzed. The flow pattern is demonstrated to depend on the ratio of the outer and inner radii of the working region. Critical conditions separating the stationary operation mode and the thermal explosion are found.
