Polymer heat exchanger design for condensing boiler

The first geometry examined, left side of Fig. 1, was a single row, coiled tube.The second geometry was a double row with the same total tube length as for the single row case. In all cases the analysis was done assuming a burner heat input rate of 26 kW, an excess air level of 25%, and exhaust gas leaving the boiler and entering the heat exchanger at 150 °C.

Experimental Determination of the Heat Recovery

Increasing the energy efficiency of a gas turbine plant can be achieved by exhaust gas heat recovery in a recovery boiler. Establishing some correlations between the parameters of the boiler and of the turbine is done usually based on mathematical models. In this paper it is determined from experimental point of view, the effectiveness of a heat recovery boiler, which operates together with a

Emission Control Technology for Stationary Internal

Stationary gas engines, typically fuelled by natural gas or propane, are widely used for prime power and for gas compression. In gas compression, the types of engines are either rich-burn or lean-burn. Rich-burn engines have an air-to-fuel ratio that is balanced, resulting in an exhaust O 2 content of about 0.5%. Lean-burn gas engines have an

Effects of exhaust gas recirculation on the thermal

In this study, a small burner called the EGR burner was used to produce the exhaust gas, as shown in Fig. 1(b). The premixed type of EGR burner was made from the same metal fiber used for the burner in the main boiler. For exhaust gas recirculation, it is necessary to prepare some additional equipment, i.e. EGR valve, pump, controllers and so on.
