Abstract: Systems and methods for generating power using hydrogen fuel, such as derived from natural gas, are provided. Feed materials are introduced into a compact hydrogen generator to produce carbon dioxide, hydrogen gas and steam. Sorbent material within the compact hydrogen generator acts to absorb carbon dioxide, forming a used sorbent. Hydrogen gas and steam are separated from the used sorbent and passed to a power generator such as a hydrogen turbine to produce power. The used sorbent is introduced into a calciner and heated to desorb carbon dioxide and form a regenerated sorbent which can be recycled to the compact hydrogen generator.

Abstract: A safety system for a heating apparatus includes an inlet for receiving input gases for combustion and a flue for expelling flue gases. A carbon monoxide sensor is also included for monitoring carbon monoxide content in the heating apparatus. The safety system also includes a pressure switch which permits the input gases to mix with the flue gases based on the information from the carbon monoxide sensor.

Abstract: Processes and systems for improvements on the efficiencies of convection ovens utilizing exhaust heat recuperation in the form of heat exchangers and premixed combustion systems, and a combination thereof. The heat exchangers and premixed combustion systems allow for increased efficiency of use of fuel and gaseous mixtures within convection oven cavities for improved heating capabilities and decreased efficiency losses.

Abstract: Methods and devices for gas mixture combustion on a surface of a permeable matrix are provided which produce or result in surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the matrix surface and decreasing concentrations of pollutant components in the combustion products. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity and configured to preheat the combustible gas mixture as it travels through the matrix. The burner includes a plurality of thermal elements having a thermal conductivity higher than and disposed in thermal transfer communication with the matrix base material. The permeable matrix base material forms a combustion surface with at least a portion of the thermal elements exposed above the combustion surface. The gas mixture is combusted at or near exit pores and channels formed at the permeable matrix material combustion surface.

Abstract: A method and system for heat recovery and/or power plant cooling, incorporating an ejector configured to transfer vapor from a generator to a condenser. The ejector includes a converging-diverging nozzle to create a low pressure zone that entrains a fluid. The ejector is within a cooling fluid cycle line in heat exchange combination with an exhaust flue gas. Two fluid flows of the fluid cycle line are mixed via the ejector into a combined fluid, wherein the ejector adjusts a temperature and/or pressure of the combined fluid. Condensing the combined fluid provides a cooling medium.

Abstract: A powered secondary air supply ranger burner and method thereof provide an efficient burner with improved heat transfer. An atmospheric range burner controls a burner flame by insulating the burner and supplying a secondary air to the burner. The secondary air concentrates a heating zone to a center of a cooking vessel to be heated by the burner flame. The secondary air also controls a size and a shape of the burner flame.

Abstract: Processes and catalyst systems are disclosed for performing Fischer-Tropsch (FT) synthesis to produce C4+ hydrocarbons, such as gasoline boiling-range hydrocarbons and/or diesel boiling-range hydrocarbons. Advantageously, catalyst systems described herein have additional activity (beyond FT activity) for in situ hydroisomerization and/or hydrocracking of wax that is generated according to the distribution of hydrocarbons obtained from the FT synthesis reaction. This not only improves the yield of hydrocarbons (e.g., C4-19 hydrocarbons) that are useful for transportation fuels, but also allows for alternative reactor types, such as a fluidized bed reactor.

Abstract: A system and method for producing ammonia at high conversion rates. The system having a fluidized bed reactor with a fluidized zone with catalyst particles. The fluidized bed reactor is preferably configured to receive a continuous flow of solid sorbent particles, nitrogen, and hydrogen, with the catalyst particles being at least ten times larger than the sorbent particles. The method allows for the nitrogen and hydrogen react on a surface of the catalyst in order to generate ammonia that is adsorbed by the sorbent particles. The method extracts the adsorbed ammonia from the sorbent particles with a sorbent regenerator to product a pure ammonia product.
