摘要:
This invention relates to a kind of clustered nozzle for gasification or combustion and its industrial applications. The clustered nozzle comprises a body case (5) and a plurality of nozzles (11) in the body case (5). The nozzle (11) includes an outer cannula (3) and an inner cannula (4) inside the outer cannula (3), a lower tubesheet (6), an upper tubesheet (7) and a cooling chamber (13). Compared with traditional coaxial double-pipe nozzles (e.g., dual-channel nozzles, triple-channel nozzles and multi-channel nozzles), the clustered nozzle for gasification or combustion has the following advantages: the length of combustion flame is shorter and the shape of flame is approximately rectangular, which help to protect the lower firebricks of the gasifier, thus prolonging their working life; the distribution of the residence time is narrower, which helps to increase the conversion rate of carbon; and the nozzle is properly-structured, which helps to prolong its working life.
摘要:
Disclosed is a multi-burner gasification reactor for gasification of slurry or pulverized hydrocarbon feed materials and industry applications thereof. Burners are disposed on the periphery or top of a gasification reactor vessel, wherein the side burners are at a small downward angle relative to the horizontal plane, which can prolong the life of refractory bricks. The operating pressure of the gasification reactor is 0.1˜12 MPa, and the operating temperature thereof is 1350° C.˜1700° C. The gasification reactor is applicable to a hot-wall lining as well as a cold-wall lining. The notable advantages of the gasification reactor are carbon conversion is high and can reach 99%, and the effective gas content is high; specific coal consumption and specific oxygen consumption are low; and it is applicable to a large coal gasification plant that processes above 3000 tons of coal per day.

A two-stage gasification apparatus coupled with heat recovery and washing includes a columnar shell (7), an entrained flow gasification chamber (1), a fixed bed gasification chamber (18), a waste heat boiler (19) and a gas cooling-washing chamber (14) set coaxially from top to bottom inside the columnar shell (7). Process nozzle chambers (3) are set at a sidewall and/or a top of the entrained flow gasification chamber (1), and process nozzles (2) are set in a nozzle chambers (3). A feed-in lock hopper (25) is set and a fixed bed gasification chamber (18). An eccentric grate (10) is set in the middle of a lower part of the fixed bed gasification chamber (18), and the grate is connected with an ash-pan (11), which is conjoined with a motor (36) via transmission mechanism. An inverse cone (22) is erected at an upper part of a cooling-washing chamber (14).

摘要:
Methods and apparatus are provided for implementing the advanced encryption standard. The apparatus comprises a first multiplexer receiving during a first cycle a data word, a substitution transformation of the data word and inverse substitution transformation of the data word to provide a first output. During the next cycle, a second multiplexer receives the first output, a mixed column transformation of the first output and an inverse mixed column transformation of the first output to provide a second output. Also in the next cycle, the second output is added to a round key to provide one round of an encoded or decoded digital word compliant with the advanced encryption standard with cycle-by-cycle throughput. The method comprises shifting a received data word and processing the shifted data word using a substitution transformation (encoding) or an inverse substitution transformation (decoding) during a first cycle in an advanced encryption standard unit of a processor. In the next cycle, the result from the first cycle is processed using a mixed column transformation (encoding) or an inverse mixed column transformation (decoding) and the result is added to a round key to provide one round compliant with the advanced encryption with cycle-by-cycle throughput.
摘要:
Embodiments of the invention provide a method of de-rate matching without NULL bits skipping. Date is received without NULLs and inputted into a LLR combining block. The history data without NULLs is buffered. Log-likelihood ratio (LLR) combining is called before de-rate matching. The output of LLR combining is de-interleaved. The reading pointer is offset to forge NULLs. Finally, de-interleaving output without NULLs is sent to a turbo decoder.
