We previously proposed the gas phase stoichiometric ratio (SRgas) as an index to evaluate NOx concentration in fuel-rich flames. The SRgas index was defined as the amount of fuel required for stoichiometric combustion/amount of gasified fuel, where the am... see more

Operational measurements of the O2 concentration in the combustion chamber of a pulverized coal boiler are not yet common practice. Operators are generally satisfied with measuring the O2 concentration in the second pass of the boiler, usually behind the ... see more

The inability of the coal mill control structure to monitor and control pulverized coal ?ow causes operational and environmental problems. The research was done to design the new control structure for coal mill in coal firing system to achieve a... see more

Rotary cement kiln is the main equipment in the cement industry that has complex dynamic behavior, where any changes will affect the quality of the product and the consumed energy. A one-dimensional model of rotary kiln is needed to understand kiln’s beha... see more

The object of research is the processes of thermal conversion of steam coal and biomass, with the aim of creating highly efficient environmentally friendly technologies for its joint combustion into fuel boiler units.One of the important problems that imp... see more

This paper presents the results of a study on modifying a pulverized coal-fired steam boiler in a 250 MWe power plant for oxygen combustion conditions. The entry point of the study is a boiler that was designed for standard air combustion. It has been pro... see more

Abstrak--Kadar NOx dan CO2 pada PLTU Eksisting di Pulau jawa tidak sesuai dengan aturan pemerintah tentang baku mutu emisi gas buang industri dan efek gas rumah kaca yang ada di Indonesia dan dunia. Kadar gas emisi buang juga harus ditekan sesuai dengan a... see more

Staged pressurized oxy-fuel combustion is an advanced technology to be employed for the combustion and carbon capturing processes. This technology is promising because of relatively low costs, low emissions and high-efficient power generation with exhaust... see more
