Used Tires are Better Fuels than Coal and Coke, Aliapur Says
A research conducted by French company Aliapur provides proof that burning used tires produce comparable energy (heat output) but less fossil CO2 emissions than burning coal or petroleum coke. Since used tires are not 100% fossil unlike coal and coke, their combustion emissions have renewable carbon or biomass fraction. Through ASTM D6866 testing, the biomass fraction of used tires was ...
Why Are CHP Closing All Over The World?
Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use individual heat sources such as electric heaters and the like. ...
Separation of CO2 during combustion of coal in a pressurised fluidised bed
The combustion of coal is accompanied by CO2 emissions. This carbon dioxide can be separated from the flue gases in the Combustion Chamber (CC) by means of adsorption on calcium oxide (carbonation) which in turn can be regenerated in a calcination process. A description of the processes and the integration in a whole power station that serves a district heating network and generates electricity ...
King Coal’s Climate Challenge
Coal is emerging as a major topic of conversation at the United Nations climate-change negotiations currently taking place in Warsaw – and rightly so. Indeed, it is a discussion that the world needs to have. The latest findings of the Intergovernmental Panel on Climate Change conclude that we are quickly using up our carbon “budget” – the amount of carbon that we can ...
A novel approach for modelling of NOx emission reduction in a tangentially fired coal boiler
In this research paper, predictive modelling of NOx emission of a 210 MW capacity pulverised coal–fired boiler and combustion parameter optimisation to reduce NOx emission in flue gas is proposed. The effects of oxygen concentration in flue gas, coal properties, coal flow, boiler load, air distribution scheme, flue gas outlet temperature and nozzle tilt were studied. The data collected from ...
Wind turbines and health
The American Lung Association's agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: "Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming." 1 Wind energy is one such solution - a clean energy source that can ...
