Fast pyrolysis processes for biomass - ScienceDirect

01/03/2000 · Biomass, with a particle size of about 5 mm, is metered into the system, where it is entrained and mixed with the recycle stream. The biomass particles, entrained in the carrier gas, enter the vortex reactor tangentially at speeds of up to 400 m/s so that the particles are forced to the reactor wall by high centrifugal forces.

A study of bonding and failure mechanisms in fuel pellets

01/02/2011 · Biomass was loaded stepwise in amounts less than 0.25 g into the unit, and then compressed at a rate of 2 mm/s until a maximum pressure of 200 MPa was reached. The pressure was released after 5 s, the piston removed, and more biomass was loaded and compressed until the pellet had the desired length of 16 mm.

Pulverised Fuel - an overview | ScienceDirect Topics

Pulverised-fuel (PF) technology is widely used for large coal-fired power plants. In such systems, the fuel particles are injected pneumatically at high velocity (the primary air is used as a carrier) through a burner nozzle into the furnace (Fig. 9.7).

Membranes | Free Full-Text | Study on the Preparation and

Ceramic membrane method for moisture recovery from flue gas of thermal power plants is of considerable interest due to its excellent selection performance and corrosion resistance. However, manufacturing costs of commercial ceramic membranes are still relatively expensive, which promotes the development of new methods for preparing low-cost ceramic membranes. In this study, a method …

A review on commercial-scale high-value products that can

08/10/2019 · Feedstock. Biomass is a renewable resource that is appropriate to produce ethanol and chemicals. Lignocellulose is the most promising biomass feedstock because of its availability and lowcost [31, 32].For example, the sugarcane and corn price have been reported to be $60.9/ton [] and $185.9/ton [], while sugarcane bagasse and corn stover prices have been estimated to be $36.38/ton [] …

Advances on the processing of Jatropha curcas towards a

01/02/2016 · Few studies have analyzed the combustion of jatropha biomass and most of them focused on the combustion performance of densified jatropha biomass,, (see Section 2.4). A study used a combustion unit designed for the jatropha tegument and concluded that the direct combustion of this feedstock was well accomplishable, reaching combustion and furnace efficiencies of 98–99 and …

Biofuel production from citrus wastes: A feasibility study

01/03/2017 · Temperature, rate of heating, shelf life of solid biomass, particle size, and gas flow rate vary in these processes. Several types of pyrolyzer are used for biomass pyrolysis in the world. Some of the major pyrolyzer (reactor) designs in use are fixed-bed, fluidized-bed, bubbling fluidized-bed, circulating fluidized-bed, ultra-rapid, rotating cone, ablative, and vacuum [127], [130], [131

RMS Olympic - Wikipedia

RMS Olympic was a British ocean liner and the lead ship of the White Star Line's trio of Olympic-class liners. Unlike the other ships in the class, Olympic had a long career spanning 24 years from 1911 to 1935. This included service as a troopship during the First World War, which gained her the nickname "Old Reliable".She returned to civilian service after the war, and served successfully as

Effects of firing coal and biomass under oxy-fuel

01/11/2013 · One of the most promising technologies for carbon capture and storage (CCS) is oxy-fuel combustion. This study uses a commercial computational fluid dynamics (CFD) code to simulate the firing of coal and biomass under air and oxy-fuel conditions in an existing full-scale 500 MW e coal-fired utility boiler. Results are presented for conventional air–coal combustion that corresponds well
