apparatus and method of furnace pressure control in regenerative reheating furnace

摘要

PURPOSE: An apparatus for controlling pressure of a regenerative heating furnace is provided to stablilize the inside pressure of a furnace by applying a bias value revising the change of the inside furnace pressure in an opening degree of a damper. CONSTITUTION: An apparatus for controlling pressure of a regenerative heating furnace comprises a damper(170), a regenerative burner(120), a heat storage combustion controller(210) and a controller(200). The damper controls the opening position of a valve and the flow rate of the heat storage heating furnace. The heat storage combustion controller produces a bias value. The controller calculates an opening output value. The controller stabilizes the inside furnace pressure of the heat storage heating furnace.
