ABSTRACT:
A regenerative heater includes a regenerator container having open opposite ends. The container contains therein a fill of heat retaining material which is permeable to the passage therethrough of gas, throughout the entire length thereof in opposite directions between the open opposite ends of the container. The fill of heat retaining material comprises solid fine granular particles having a low thermal conductivity. A heat source is positioned adjacent the first end of the fill of heat retaining material. At least one blower is provided for circulating gas in opposite directions through the entire length of the fill of heat retaining material and across substantially the entire cross-section thereof. A charging flow of gas is first circulated in a first direction through the fill of heat retaining material, such that the charging flow of gas is heated by the heat source and then passes through the heat retaining material while transferring heat to the heat retaining material. Then, a discharging flow of gas is passed in a second opposite direction through the fill of heat retaining material, such that the discharging flow of gas receives heat from the fill of heat retaining material. At least the charging flow of gas is entirely enclosed in a completely closed circulation path including the interior of the regenerator container.
