Minimization of start-up time of sojitz kelanitissa combined cycle power plant

Manickasivam P [Thesis-Abstract]

There are only three combined cycle power plants in Sri Lanka. Ceylon Electricity Board owns one power plant, and private companies own the other two. Combined cycle power plants start-ups can be divided into three ...
Dynamic cooling load analysis on indoor thermal comfort state in passenger trains

Kodituwakku TP [Thesis-Abstract]

Increasing passenger density makes indoor state of train compartments not thermally comfortable. Air conditioned train compartments have been introduced to provide comfortable pleasant interior environment to the passengers. ...
Evaluating the heat recovery options from the generated oily sludge in thermal power plants

Charithananda SPM [Thesis-Abstract]

Oily sludge is a process waste of thermal power plants that use heavy fuel oil for power generation. At present, the oily sludge is sold or incinerated from the power stations belonging to Ceylon Electricity Board. Since ...
Economic feasibility of a hybrid energy system for Kalpitiya peninsula from selected technologies

Atapattu KR [Thesis-Abstract]

Economic feasibility of having a grid connected hybrid energy system, consist of wind, solar, biomass (rice husk) & municipal solid waste (MSW) technologies for Kalpitiya peninsula was studied. Four (04) different microgrid ...
Optimization of soot blowing operation for Lakvijaya coal power plant in Sri Lanka

Sarathkumara SCM [Thesis-Full-text]

An optimization of soot blowing operation was carried out for Unit No.3 for Lakvijaya Power Plant in Sri Lanka. Average coal flow rate and flue gas temperature are the key indicators of boiler performance with soot blowing ...
Low grade thermal energy harvesting from thermo-acoustic generator

Rathnayake, RKA [Thesis-Full-text]

A thermoacoustic generator is an energy conversion device. It converts thermal energy into acoustic energy by using the stack. That is porous medium that contains a large number of channels. The acoustic energy can be ...
Feasibility assessment of the applicability of tri-generation systems in the apparel industry in Sri Lanka : a case study

Abeynayake, AMNS [Thesis-Full-text]

In this study, the technical and financial performances of the first tri-generation plant installed in Sri Lanka were evaluated. This plant was installed at Tee Jay Lanka PLC; a leading knit fabric manufacturer in the local ...
Comparison of biomass cookstoves in Sri Lanka

Chandrasena, RIK [Thesis-Full-text]

Biomass plays an important role in Sri Lanka Energy Sector. The consumption of biomass in the commercial and household sector is declining due the popularity of fossil fuels. Consumption of biomass is getting less popular ...
