Optimization of Boiler Blowdown and Blowdown Heat

Blowdown in Boiler | Boiler Blowdown Calculation Formula

Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.

Blowdown in Boiler | Boiler Blowdown Calculation Formula

The results indicate that using blowdown recovery technique, the net generated power increases 0.72%. Also energy and exergy efficiency of the system increase by 0.23 and 0.22, respectively. The optimization results show that temperature and pressure of boiler outlet stream have a higher effect on the exergy efficiency of the system in respect to the other decision variables.

Best Management Practice #8: Steam Boiler Systems

Blowdown heat exchangers are a useful technology to consider because they allow some of the heat contained in the boiler blowdown to be transferred to the boiler feed water. This also allows for the production of low pressure steam, which can be returned to the steam system or used in the de-aeration of boiler feed water.

For boiler optimisation it is important to address both the combustion system, and the steam and feed-water systems. Combustion efficiency Combustion efficiency indicates the flue gas loss. Boiler efficiency also includes the blowdown and stand-by losses. Whether comparing new or existing boilers, their most efficient operating point is usually

Recover Heat from Boiler Blowdown - Energy

Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers. The following table shows the potential for heat recovery from boiler blowdown. Example

What is Boiler Blowdown ? - Surface Blowdown - Bottom Blowdown

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of
