Abstract: The invention creates a new type of scrubbers: drum scrubber. In the drum scrubber, processed gas passes through a wet fiber filter, but unlike previously invented fiber-bed scrubber, the fiber is constantly cleaned. The cleaning is achieved by using filter material as a surface of the rotating drum, partially immerged in a liquid. While periodic immersion of filter fiber in liquid might achieve appropriate particle removal for some applications, better cleaning is provided by creating a reverse flow of liquid through the filter material. In addition, filter material could be sprayed with liquid from either within the drum or from outside of the drum, or both. Also, ultrasound could be used to release particles trapped within fibers while fibers are immerged in the liquid. This solves the plugging problem normally associated with wet filter and allows its use in most applications, including applications with a high dust load.

Abstract: The invention creates a new type of heat exchangers—Bent-Tube Heat Exchanger. It solves thermal expansion problem, allowing airtight connections for both sides of tube connection to tube sheets instead of a sliding connection on one side. Additionally, unlike in spiral-tube heat exchangers, the use of straight tube sections allows for uniform tube spacing and having the same length for all parallel tubes.

Abstract: Inexpensive process for synthetic fuel production, contained fluidized-bed burner, pyrolysis reactor with layer of fuel & hot material mixture and hot material circulation system.Fuel is heating up to pyrolysis temperature by surrounded hot material in layer. Volatile matter, evacuated from pyrolyser to cooler, is used for synthetic fuel production. Warm mixture of char and bed material is returned to fluidized bed for burning. Heat of burned char used for circulated material heat up and for steam generation. Hot material from fluidized bed is transported to pyrolyser and, after mixing with fuel form layer in pyrolyser.The process may be used for utilization of extremely wide range of fuels. For fuels with low value of fixed carbon content, oil shale for example, the process may be used solely for synthetic fuel production; for coals only part of fuel energy may be transfer to synthetic fuel, rest have to be used for steam generation.
