Temperature control system for pyrolysis furnace

摘要: A batch-type pyrolysis furnace fired by a main gas burner and an afterburner, is effectively safeguarded from explosions runaway fires due to undue build-up of flammable vapors within its chamber, the simple expedient maintaining fire under controlled temperature conditions in chamber. This done dual-stage control system requiring three thermocouples, one (first) second exhaust stack downstream third upstream afterburner vent passage ("throat") connecting chamber with The first thermocouple senses ambient, essentially instantaneous at that location. effectiveness system, large measure, derives unexpected difference temperatures sensed thermocouples.
