US4659305A - Flue gas recirculation system for fire tube

Jun 15, 1994 · Normal operating temperature in the combustion zone is approximately 2,000 - 3,000 degF. The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe. Figure 2-1 is a diagram of the process. Combustion air is supplied from two sources, the primary and secondary air systems.

SECTION 235216 - CONDENSING BOILERS

In this work, the modeling of the heat transfer between flue gas and water in a fire-tube boiler is considered. In the literature, a comprehensive modeling for fire-tube boilers has not been treated. Generally, the few models found are focused to one aspect of the fire-tube boiler performance as the gas/fire side or the water/steam side, and

DEVELOPMENTAL DESIGN OF A LABORATORY FIRE-TUBE …

A flue gas recirculation system for fire tube boilers includes a duct connected to the boiler gas discharge stack and to a fan. Another duct couples the fan to a specially designed burner in the boiler. Recirculated flue gas is injected downstream of the fuel/air mixture in the burner and cools the flame leading to substantially reduce the NO x content in the boiler stack emissions.

CFD simulation of fuel/flue gas section of the fire-tube

Steam boilers are used to generate steam. Steam boiler equipment typically has fuel/flue gas and water/steam sections. Based on the flow of flue gases and water/steam, they are classified as water-tube boilers and fire-tube boilers. In water-tube boilers, the shell side contains the fuel and hot flue gases and water flows inside the tubes.
