Combustion jet pumps ingest waste heat gases from power plant engines and boilers to boost their pressure for the ultimate low temperature utilization of the captured heat for heating homes, full-year hot houses, sterilization purposes, recreational hot water, absorption refrigeration and the like.

Combustion jet pumps ingest waste heat gases from power plant engines and boilers to boost their pressure for the ultimate low temperature utilization of the captured heat for heating homes, full-year hot houses, sterilization purposes, recreational hot water, absorption refrigeration and the like. Jet pump energy is sustained from the incineration of solids, liquids and gases and vapors or simply from burning fuels. This is the energy needed to transport the reaction products to the point of heat utilization and to optimize the heat transfer to that point. Sequent jet pumps raise and preserve energy levels. Crypto-steady and special jet pumps increase pumping efficiency. The distribution conduit accepts fluidized solids, liquids, gases and vapors in multiphase flow. Temperature modulation and flow augmentation takes place by water injection. Macro solids such as dried sewage waste are removed by cyclone separation. Micro particles remain entrained and pass out with waste condensate just beyond each point of final heat utilization to recharge the water table. The non-condensible gases separated at this point are treated for pollution control. Further, jet pump reactions are controlled to yield fuel gas as necessary to power jet pumps or other use. In all these effects introduced sequentially, the available energy necessary to provide the flow energy, for the continuously distributed heating medium, is first extracted from fuel and fuel-like additions to the stream. As all energy, any way, finally converts to heat, which in this case is retained or recaptured in the flow, the captured heat is practically 90% available at the point of low temperature utilization. The jet pump for coal gasification is also disclosed as are examples of coal gasification and hydrogen production.

The method of generating a hot high pressure fluid stream comprising the steps of combustion of an oxygen bearing fluid and fuel, introducing a carbonaceous water bearing material into a pressure zone without substantial loss in pressure, transferring heat from said stream to react with and to evaporate the water from said material, separating the dried and unreacted parts of said material from said zone while continuing to substantially maintain said pressure in the remanent flow of product gas and water vapor, while continuing high static pressure in said flow after separating said parts for the optimal utilization of the heat content in said flow, and further whereby the delivery of product gas with minimal surplus steam is controlled by effecting, at the most, four independently varied steam sources including steam by direct heat transfer from at least two combustion reactions within the system, and further, whereby said combustion takes place in a confined space to deliver a transonic jet from a nozzle which emanates from said space into a mixing zone conforming to the low static pressure of said jet for receiving said material introduced at very low velocity in the range of 100 to 200 feet per second to interact violently with the combustion products in said jet.
