1. Nova Scotia Power Inc.’s 165 MWe CFBC plant at Point Aconi remains the largest fluidized bed facility in Canada. The plant is operating normally and firing a mixture of petroleum coke and coal.
2. South Shore Power operates one 25 MWe BFB boiler firing wood waste from a paper mill. The facility is located in Brooklyn, Nova Scotia.
3. To extract oil from the oil sands, several companies operate fluidized bed cokers for bitumen upgrading in Alberta. The companies include Syncrude, Suncor, Canadian Natural Resources Ltd. and others. These are large-scale fluidized bed facilities. As oil prices continue to rise, more oil sands projects will be initiated. It is thus predicted that more fluidized bed cokers will be built and operated.
A high proportion of the combustible content of wood and other biomass fuels burns in the form of volatile compounds. A large proportion of the combustion air requirement, therefore, is added above the fuel in stoker and other conventional combustion small biomass boiler vertical wood boilers as overfire air.
According to the central environmental supervision feedback on the issues raised in item 50: "Mudanjiang 108 wood processing enterprises, 69 there is the issue of illegal construction projects, companies supporting more than 114 small biomass boiler vertical wood boilers for small hand-burning stove, black smoke very serious people to report complaints, "the rectification of the problem. Mudanjiang City, Heilongjiang Province, the municipal government attaches great importance to conduct a comprehensive renovation work for small coal-fired boilers.
The beginning of tasks to carry out, Municipal Environmental Protection Bureau of Mudanjiang City Center 108 existing wood processing enterprises in coal-fired boiler equipment to be checked. Inspection and found 69 illegal construction projects there is a problem, companies supporting more than 114 boilers for small hand-burning stove, black smoke is very serious. To date, there are 65 companies to complete the record, four enterprises waste industry. By Trade and Industry Bureau of Quality Supervision and verification, 114 sets of small boilers of this regulation in the wood enterprises, has completed the transformation units 62, cancellation, revocation 23 units, idle shutdown, waste industry 26, and removal of three. Wherein Yangming boilers zone 97 (where the 58 transformation is complete, the boiler cancellation, revocation table 21, the idle shutdown, industry waste boiler 18); boilers zone 12 (where the grid and transformation of the two, the idle shutdown the six, cancellation of Taiwan, has been demolished three); Dongan District 3 boilers (in which the transformation is complete for two, small boilers cancellation Taiwan); Xi'an area, Edmonton area each in Taiwan, the company has waste industry.
Next, the relevant departments will conscientiously implement the municipal government on Ecological Construction Decision deployment environment, learn from experience and practice fraternal units, work together to tackle, wood enterprises continue to consolidate and expand the results of pollution remediation, pollution prevention and determined to win the battle , to create the sky bluer, more green mountains, clear water and more beautiful environment, Mudanjiang modernization and make due contributions.
As a clean coal combustion technology, the Circulating Fluidized Bed (CFB) technology has been successfully used in small biomass boiler vertical wood boilers in Tanzania. The various types of solid fuel combustion systems historically available, such as wood poles and timber fired boilers have distinct and specific advantages and disadvantages.
