Landslides happen in all geographic areas of the state according to a variety of stipulations and triggering methods that come with storms, earthquakes, and human actions. Landslides within the usa lead to an anticipated commonplace of 25 to 50 deaths every year and price $1 to three billion according to 12 months.

Abs. 051 bar) backpressure is achieved by the use of freshwater within a 59◦ F to 68◦ F (15◦ C to 20◦ C) inlet temperature range. The machine house for the 2 approximate 785-MW steam turbine-generators is closely arranged to the boiler buildings to keep steam piping as short as possible. The boiler buildings enclose also the SCRs and recuperative air preheaters. The flue gases leave the boiler buildings to enter the electrostatic precipitators and then the desulfurization system. The flue gases are reheated before being discharged through the stack.
The generated feedwater heating by flue gases reduces the demand of feedwater heating by steam turbine extraction steam.  Therefore, when applying a cooling tower instead of fresh water cooling with a resulting increase in the LP steam turbine backpressure, the plant efficiency will be lower, but utilizing the flue gas heater for heat recovery will at least partially recover some of this plant efficiency reduction. Figure 2-5 shows the flue gas discharge pattern from a stack versus from a cooling tower.
For larger units or lower backpressures, even a 6-flow instead of 4-flow LP turbine arrangement could be considered. cls 30 • April 8, 2003 T1: IML/FCH 20:15 Char Count= 0 CLEAN AND EFFICIENT COAL-FIRED POWER PLANTS FIGURE 2-1.

This efficiency already includes the steam supply for the steam turbines driving the boiler feedwater pumps but not the boiler efficiency and power plant auxiliary losses.
