This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

At industrial enterprises built in the former USSR, capacity of installed boiler equipment was determined based on projected growth heat loads. Due to decline production enterprises, consumption thermal energy is also reduced, and there a problem prolonged operation steam hot water boilers at minimum The operational personnel different solve this practice their own way, without being aware poss...

In this study two commonly used steels in boiler plants, i.e. (SAE-213) T-22 and SA516 (Grade-70) were coated with different thermal spray processes namely HVOF and cold spray. The coating powder used was made up of NiCrTiCRe powder. The performance of the coated as well as uncoated material was investigated using a pin-on-disc machine [Model: Wear and Friction Monitor Tester TR-20], supplied b...

Oil paint is a type of chemical colors dependent on the type and composition make multiple risks for our health. The aim of this study was to investigate the effects of oil paint vapor on thermal pain sensitivity in male rats. In this laboratory experimental study, male rats were randomly divided to control and animals exposed to oil paint vapor. Data were analyzed using ANOVA. The results indi...

The basic need of living things that is very important and cannot be separated water. Various industrial activities require water for processing such as the palm oil industry, industry required to use with good conditions proper chemical treatment. power plant at PT. Socfindo Seunagan, requires steam needs from boiler. Boiler a closed place produce heating boiler system, among others, consists ...

This paper investigates the optimal configuration of micro combustion engines (kWel or kWth), the associated volume of thermal heat storage and the thermal capacity of an additional boiler (kWth) for heat supply in residential buildings with 30 units, which have been built in Vienna (Austria) during different construction periods (before 1919 to 2011). The target function for the configuration ...

The usage of biomass fuel for heat and power production is growing due to an increasing demand for replacing of fossil energy sources with renewable energy. Typical biomass fuel is usually a blend of different batches, for example, spruce bark and dry woodchips with varying moisture content between 30% and 55%. This varying moisture content of the fuel results in uncertainty in the energy conte...

In a fertilizer plant, the steam boiler is the most important component. In order to keep the plant operating in the effective mode, the boiler efficiency must be observed continuously by several operators. When the trend of the boiler efficiency is going down, they may adjust the controlling parameters of the boiler to increase its efficiency. Since manual operation usually leads to unexpected...
