摘要:
Pyrolyzing gasification system and method of use including primary combustion of non-uniform solid fuels such as biomass and solid wastes within a refractory lined gasifier, secondary combustion of primary combustion gas within a staged, cyclonic, refractory lined oxidizer, and heat energy recovery from the oxidized flue gas within an indirect air-to-air all-ceramic heat exchanger or external combustion engine. Primary combustion occurs at low substoichiometric air percentages of 10-30 percent and at temperatures below 1000 degrees F. Secondary combustion is staged and controlled for low NOx formation and prevention of formation of CO, hydrocarbons, and VOCs. The gasifier includes a furnace bed segmented into individual cells, each cell is independently monitored using a ramp temperature probe, and provided with controlled air injection. Gasifier air injection includes tuyere arrays, lances, or both. The oxidizer includes three serially aligned stages separated by air injecting baffles, and ability to adjust the exit air temperature.
摘要:
A gasifier and gasifier system based on the gasifier, which contains as a major component, a novel feed system for feeding organic materials into the burn pile of the gasifier. The gasifier feed system is a horizontal auger driven feed system that feeds directly through a ceramic elbow into the furnace without having to auger the feed through significant vertical elevations.

High temperature intermittently sealable refractory tile and controlled air continuous gasifiers (rotary kilns) that are manufactured using such refractory tile, waste to energy systems that have such gasifiers as part of the system, and processes in which such waste to energy systems are used, for example, co-generation steam and power plants using biomass as the fuel for the process.

Landfill gas combustion and landfill leachate evaporation systems and the use of forest products or some such fuel to fire a gasifier that will eventually provide energy. Novel all-ceramic heat exchangers, systems in which they are used, and processes that can be handled by such systems.
摘要:
Ceramic cowlings that are used as the connection between a hot gas source and a Stirling engine or a turbine. The ceramic cowling is designed and fabricated with non-dusting, high temperature, dense, low thermal expansion ceramic. It must also be highly resistant to thermal shock. Also, a combination of a ceramic cowling and a shroud for covering and holding the ceramic cowling on a Stirling engine or turbine such that hot gases can flow through the ceramic cowling and into the heat exchanger coil of the Stirling engine and exhaust in a controllable manner. A method of enhancing the power efficiency of a Stirling engine and with systems including the use of at least one enhanced power Stirling engine.

摘要:
Sail support device comprising a plurality of slides (1) adapted to be retained to a sail (21) by webbing (8A). The slides (1) are accommodated in a groove (3) of a track member adapted for mounting on a stay (23). Each slide (1) has an elongate hollow body (2) with a longitudinal aperture through the wall thereof enabling an eye (20) formed by the webbing (8A) to be inserted into the body (2). A pin (9A) is insertable into the body (2) and through the eye (20) and locates in the body (2) to anchor the webbing (8A) thereto. A gate section (22) of the track member is rotatable about a connector joining sections (4A, 4B) of the track member together to expose open ends of grooves (3) enabling the slides (1) to be slid thereinto. With alignment of the grooves (3) of the gate section (22) with those of the track member, the sail (21) can be raised with slides (1) travelling up the full length of the track member.
