Dynamics of steam accumulation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Steam accumulators are applied as buffers between steam generators and consumers in cases of different steam production and consumption rates. The steam accumulator is filled with water and steam and it operates with a ...
Research on air pressure drop in helically-finned tube heat exchangers
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
In order to establish a reliable procedure for estimation of air pressure drop, extensive investigation of the open literature has been conducted. The equations from mostly cited literature sources were tested against the ...
Thermal-hydraulic analysis of a steam boiler with rifled evaporating tubes
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Rifled evaporating tubes are applied in the steam boilers with the aim to increase the steam-water mixture turbulization and to prevent the burnout of tubes walls. The rifled evaporating tubes and the working fluid forced ...
A computer code for the prediction of mill gases and hot air distribution between burners' sections at the utility boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections. These are the ...
Low-temperature convective drying of apple cubes
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The paper presents results of an experimental investigation of convective drying of Idared apple in full recirculation laboratory scale dryer. The experiments were conducted with cube-shaped apple samples (side length 10 ...
Experimental evaluation of desuperheating and oil cooling process through liquid injection in two-staged ammonia refrigeration systems with screw compressors
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper examines the problem of achieving desuperheating through liquid injection in two-staged refrigeration systems based on screw compressors. The oil cooling process by refrigerant injection is also included. The ...
Possibilities for reconstruction of existing steam boilers for the purpose of using exhaust gases from 14 MW or 17 MW gas turbine
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Within the energy system in Methanol vinegar complex (MVC) in Kikinda, beside process boiler and auxiliary equipment, there are three equal steam boilers made by "Minel Kotlogradnja", provided for combustion of natural ...
Assessing the impact of primary measures for NOx reduction on the thermal power plant steam boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The European normatives prescribe content of 200 mg/Nm(3) NO for pulverized coal combusting power plants. In order to reduce content of NOx in Serbian thermal power plant (TPP) square Kostolac B square it's necessary to ...
Numerical prediction of processes for clean and efficient combustion of pulverized coal in power plants
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Coal-fired power plant technologies should provide higher efficiency of energy conversion, reduction of pollutants emission, operation of facilities in a wide range of loads and efficient utilization of variable quality ...
Novel method for validation of experimental data for direct contact condensers with zero vapor outflow
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Although contact condensers are extensively used for various industrial applications, procedures for calculation and sizing these vessels are scarce in the open literature. However, before new and reliable calculation ...
