Analysis of Medical Waste Incinerator Performance Based on Fuel Consumption and Cycle Times
Open accessAbstract
A detailed assessment of an incinerator based on fuel consumption and cycle time data is presented in this paper.The study was conducted at Temeke district hospital for 22 months consecutively covering 654 days of daily data collection on waste loading rate fuel consumption and cycle times.The composition for the medical waste incinerated varied between 15% and 35% for sharps waste and between 65% and 85% for other waste, with mean values of 25% and 75%, respectively.The results revealed poor performance of the incinerator due to higher fuel consumption (above 30 L/cycle).The incineration cycle times were observed to range between 2 and 4 hours, all of which were too high for the loading rates observed (55 -214 kg).A strong dependency of diesel oil consumption on cycle time was observed due to lack of temperature control leading to continuous fuel flow into the burners.The incineration capacity was very low compared to other incinerators in terms of tons per year.This paper gives an insight on the factors affecting incinerator performance assessed based on diesel oil consumption and cycle times.It can be generalized that the incinerator performance was poor due to several factors ranging from poor incinerator design, operator skills, waste management practices, waste storage practices, etc.The hospital was advised to install a new incinerator with short incineration cycle time (30 -40 minutes) and lower fuel consumption (10 L/cycle) at a loading rate of 200 kg/cycle.

The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Normally, incinerators are operated at high temperature between 300 ∘ C and 1100 ∘ C based on volume and type of waste, incinerator, and fuel used [5].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
