BHEL and IITM organize 3-day International workshop on CFBC boilers

Tiruchirappalli: The Indian Institute of Technology, Madras (IITM) and the FBC & HRSG (Fluidised Bed Combustion and Heat Recovery Steam Generators) group of Bharat Heavy Electricals Limited (BHEL), Tiruchirappalli jointly conducted a three day international workshop on 'Fluid Dynamic Scaling, Design and Instrumentation of Cold Models and Practical issues of CFBC Boilers'.

The International workshop was attended by FBC experts from Sweden, Germany, Canada and Australia in addition to professors from IITM, NIT, Tiruchirappalli, BHEL’s Corporate R&D officials and engineering groups from BHEL, Tiruchirappalli.

Explaining BHEL’s involvement in the development of FBC technology, A V Krishnan, Executive Director, BHEL, Tiruchirappalli, said that BHEL pioneered the research in Fluidised bed combustion as early as 1975.

He said that the company had built test facilities of Bubbling-bed and Circulating Fluidised-bed, for testing newer fuels and the data was used in the design of commercial units. He also said that BHEL was currently executing many CFBC projects of 125 MWe capcity, firing medium-to-high sulphur lignite of Gujarat and Rajasthan and two projects at Neyveli of 250 MWe capacity CFBC units.

Delivering the keynote address on the inaugural session, Mr. A V Krishnan, said that, as global climatic change programmes being pressed hard, BHEL’s quest had been towards clean energy and clean combustion. Mr STH Rizvi, ED (Coporate Engineering and Product Development-CEPD), BHEL, New Delhi, in his special address, said that BHEL’s responses to climate change were IGCC (Integrated Gasifier Combined Cycle) and supercritical technology.

Pointing out BHEL’s readiness in meeting the country’s power requirement by increasing its manufacturing capacity, Mr Rizvi said that every one per cent increase in GDP of the nation could be achieved with two percent increase in energy requirement.

Mr M Karunakara Reddy, General Manager (FBC& HRSG) welcomed the gathering and briefed about the developmental growth of CFBC technology.

Mr. A V Krishnan urged the experts attending the workshop to deliberate all technical issues connected with CFBC technology and wanted the 'scale-down' studies to optimize the performance of the commercial plant by as closely representing the operating characteristics as possible in the scaled-down model.

More 'green' biomass boilers could be on the way

Bradford Council hopes to build a new storage unit in the city’s Peel Park to house the wood chippings it needs to fuel two biomass boilers.

The boilers were installed at City Hall and Ilkley Town Hall last year as part of the Council’s pledge to reduce its carbon emissions by 20 per cent by 2010/11.

Many of the wood chippings used to power the boilers come from timber taken from the authority’s estates and woodlands.

In January last year the Telegraph & Argus reported that the district’s nine civic Christmas trees were turned into chippings to fuel the wood-burning boilers. In addition, trees cut down as part of a restoration of Roberts Park in Saltaire have been turned into woodchips to be used in the boilers.

Now the Council wants to increase its storage facilities to help it save nearly £60,000 a year through the new technology.

The authority is also considering installing similar biomass boilers at other Council buildings in a drive to cut its emissions.

A Council spokesman said: “There is a planning application to increase the size of a shed at Peel Park which stores wood chippings. The wood chippings are used in biomass boilers at Bradford City Hall and Ilkley Town Hall.

“The boilers are fuelled by the woodchips which are collected from Leisure Services. The boiler at City Hall could provide up to £50,000 per year savings and up to £7,000 per year at Ilkley Town Hall.

“The additional storage for wood chippings at Peel Park would give us the opportunity to try the biomass technology at additional locations and other Council buildings.”

The Council also wants to deliver 20 per cent of the power it uses through renewable sources by 2020. Solar power technology is already in place at Bradford Central Library.

The target date for the application to be determined is Tuesday, September 15.
