Minimization of Major Air Pollutants from Sewage Sludge Fluid Bed Incinerators
ABSTRACT Emissions of major air pollutants including carbon monoxide (CO), nitrogen oxides (NOx) and mercury (Hg) were studied at two sewage sludge fluidized bed combustion (FBC) plants. Both the North West Bergen (NWB) County Utility Authority and the Little Miami (LM) plants have air pollution control systems (APCS) that are of the wet type. Various operating conditions such as ...

Hydrogen production through chemical looping using NiO/NiAl2O4 as oxygen carrier
A new autothermal route to produce hydrogen from natural gas via chemical looping technology was investigated. Nowadays, 90% of the worldwide produced hydrogen comes from fossil fuels, the most common process being Steam Methane Reforming (SMR), which produces several kg of CO2 equivalent per kg of hydrogen. In classic SMR technology, most of the greenhouse gases are vented to the atmosphere. ...

Influence of bed height on the quality of rice husk ash in a fluidised bed combustor
The purpose of this study was to investigate the effect of bed height on the quality of rice husk ash in a 210–mm diameter pilot scale fluidised bed combustor. The degree of rice husk burning in the fluidised bed could be deduced from the temperature of the combustor and the particle size of the resulting ash. The turbulence in the bed would break down the char skeleton of the rice husk ...

Low-volatile coal combustion technologies in Vietnam: issues and strategies
Vietnam has planned to install a number of coal-fired power plants with unit's capacity of up to 600 MW. Present experience shows that available low volatile anthracite coal is difficult to burn in the PC fired boilers. In this paper, the CFB combustion technology is proposed based on the experiences of coal-fired power plants around the world used similar coal characteristics. Later, a ...

The impacts of technological learning on the optimum technology mix: simulations for the Indian power sector
For the investigation of the optimum technology mix of any country, which is clearly an issue of dynamic nature, technological learning and economies of scale play a significant role. Hence, in this paper's long term planning exercise for the Indian power sector (2000-2025), our simulation analysis specifically includes the impacts of technological learning on the optimal inter-temporal choice of ...

Fluidised bed combustion and gasification of rice husk and rice straw – a state of art review
Rice is cultivated in all the main regions of world. The worldwide annual rice production is 666 million tons for the year 2008. The combustion and gasification of rice husk/rice straw in fluidised bed reactors seems to be an attractive possibility of future for power generation, the solution of waste disposal problems and the reduction of greenhouse gases. In this paper, overview of fluidised ...

What are the types of incinerators available?
Incineration is a viable alternative to Landfill. An incinerator can destroy and remove at least 99.99 percent of each harmful chemical in the waste it processes. When some extremely harmful chemicals are present, EPA requires that an incinerator show it can destroy and remove at least 99.9999 percent of contaminants in the waste. Ash remaining at the bottom of the combustion chambers likely ...
