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 ...

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 ...

Some theoretical fundamentals of catalytic fuel combustion
In the following paper, the special features of catalytic combustion, which are distinct from the developed theory of flame combustion are considered. They are connected with the properties and characteristics of catalysts, the developed surface for reaction and the comparatively low catalysts' temperatures. They determine the rate of catalytic reaction and the corresponding three main regions 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 ...

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 ...

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 ...

Feasibility analysis for biomass in cities, counties and facilities
The commercial waste industry includes all those who collect waste from the simplest “collect waste and transport to a landfill” to the more complex “collect waste and process into re-usable components and energy.” This article will cover how we can collect material and fuel a clean energy system for our immediate future, while saving clean water and air. Why Use Biomass? ...

How Long Can The Straw Pellets Burn Made By The Straw Pellet Machine
The straw pellet machine directly compresses the crushed straw, and it does not produce chemical changes during the production process, just simple high-temperature compression. The advantage of this biomass pellet machine equipment is that no additives added in the production process, the process is simple and easy to operate, and the finished product not polluted during the combustion process. ...

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. ...

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 ...

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 ...

Case study - Coater replaces old oxidizers With energy efficient systems
Overview Emission control and the operating costs associated with meeting environmental regulations were nothing new for the Coated Products Division of Brady Corp. The company has been manufacturing coated films for nearly 60 years, demonstrating over that time a commitment to pollution prevention and emission reduction programs. But these considerations were magnified when the Milwaukee ...
