Increasing Cooling Towers Heat Capacity by Flue Gas Introduction
نویسنده
چکیده مقاله:
In this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. In the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. As a result of this process, the draft of the cooling tower is increased. The additional produced draft depends on the ambient temperature and the amount of heating.
The results of the study show that the heating process is more effective in the hot weather than in the cold weather.

متن کاملFlue Gas Cooling
When waste heat is not utilized, cooling of flue gases in special cooling chambers becomes necessary, if the dust':'collecting and associated equipment is constructed of metal. The two most common methods of cooling are by dilution with ambient air, and by evaporation of water in the gas stream. Usually, they are combined. Load sharing depends largely on acceptable visibility of stack effluvia ...
متن کاملFeasibility Study of the Thermal Performance Improvement of Natural Draft Dry Cooling Towers Due to Flue Gas Injection
In steam power plants, any improvement in the cooling towers thermal performance will cause the condenser's temperature to decrease; which in turn enhances the power plant's efficiency. Due to water shortage, many power plants all around the world rely on natural draft dry cooling towers (Heller type). In these cooling towers, condenser's exit hot water is pumped to vertical or horizontal finne...
متن کاملMINLP Optimization of Cooling Towers
This paper presents a mixed-integer nonlinear programming (MINLP) model for the optimal design of mechanical counter-flow cooling towers, subjected to standard design constraints. The objective function consists of the minimization of the total annual cost, which includes the capital cost of the cooling tower (that depends on the filling material and the air flowrate) and the operating cost (th...
متن کاملFlue Gas Conditioning
Flue gas conditioning (FGC) systems offer an effective option for control of Particulate Matter (PM) emissions and enhances the performance of the Electrostatic Precipitators (EPs) when using coal of different properties. The increasing environmental awareness and the mandate of the Environmental Protection Agencies (EPA) in various countries to thermal power stations using coal-fired boilers f...
