Abstract: An automatic biomass fuel burning heating device and method comprising a burn chamber having a sloped floor and a feed auger supplying biomass fuel to be burned. A burn chamber having a feed auger opening in a burn chamber wall. An ash auger to carry ash away from a base of said sloped floor and a heat exchanger carries supply air through the burn chamber to heat a space such as a brooder house. A fan drives supply air through the heat exchanger and a control regulates the speed of the fan and the operation of the feed auger. The control maintain supply air into the brooder house at a constant set temperature by varying the volume rate of air flow based on air inlet temperature and the temperature in the burn chamber.

Abstract: An air cycle environmental control system for high pressure water separation omits a condenser heat exchanger and includes a reheater capable of placing compressed air in a heat exchange process to condense water vapor. A first turbine is in direct flow communication with the reheater, while the first turbine is capable of condensing water vapor from the compressed air. A water extractor is in flow communication with the first turbine and the reheater, while a second turbine is downstream of the reheater. The second turbine is capable of cooling a reheated, dehumidified air from the reheater to produce a conditioned air for supply to an enclosure. A method of water separation from a high pressure water vapor bearing air omits a step of condensing water vapor in a condenser heat exchanger and includes the steps of cooling a compressed air in a reheater heat exchanger such that the compressed air becomes a cold air. Water vapor is then condensed from the cold air to become a dehumidified air.

Abstract: An apparatus for replacing particles in a process that transfers particles is disclosed. The apparatus employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. The apparatus allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.
