Abstract

Control system for a countercurrent-operated tunnel furnace with smoke-gas control by vacuum in the heating zone and with an upper and a lower temperature limitation carrying out the control of the smoke-gas line, furthermore with a combustion zone regulated as a function of temperature, with rapid cooling regulated as a function of temperature and located at the start of the cooling zone, and with direct suction regulated as a function of temperature and an inflow-air fan regulated as a function of pressure and located at the end of the cooling zone, wherein, according to the invention, when an upper or a lower limit value of the temperature is reached at a point of the cooling zone between the rapid cooling (8) and first direct suction (9), the desired pressure value of the inflow-air fan (11) is adjusted upwards or downwards and thus ensures a variation of the pressure gradient in the furnace, by means of which the control of the smoke-gas fan is influenced. <IMAGE>
