how much is the ph value of the steam boiler condensed water


Thermal power station - Wikipedia

The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38%, with state-of-the-art fossil fuel plants

Formulation of Corrosion Inhibitors | IntechOpen

Aug 20, 2019 · Supplemental water for a boiler with high pressure is restricted to the minimal pH of 8.5 to reduce the corrosion of iron at room temperature, and the acceptable pH value should be at the range of 9.2–9.5. For Cu alloys, the optimal pH value is from 8.5 to 9.2.

Water Handbook - Measurement of Steam Purity | SUEZ

The exact ratio of sodium to dissolved solids in the boiler water and consequently in the steam can be determined for each plant but is approximately 1:3 for most plants (i.e., for each 0.1 ppm of sodium in the steam there is approximately 0.3 ppm of dissolved solids present).

Engine efficiency - Wikipedia

Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work.There are two classifications of thermal engines- Internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and; External combustion engines (steam piston, steam turbine, and the Stirling cycle engine).

Hydrazine | N2H4 - PubChem

Hydrazine is a highly reactive base and reducing agent used in many industrial and medical applications. In biological applications, hydrazine and its derivatives exhibit antidepressant properties by inhibiting monoamine oxidase (MAO), an enzyme that catalyzes the deamination and inactivation of certain stimulatory neurotransmitters such as norepinephrine and dopamine.

Rankine Cycle - an overview | ScienceDirect Topics

The high-pressure liquid enters a boiler, where it is heated at constant pressure to the compressed liquid (Step 2-3) and two-phase (i.e., water and steam) mixture (Step 3-4). The steam is then passed through the superheaters, where it superheated (Step 4-5). The steam is then expanded through a turbine to generate power (Step 5-6).

Water Handbook - Condensate System Corrosion | SUEZ

The fate of the ferrous ion (Fe2+) depends on condensate temperature, pH, and flow conditions. At low temperatures, Fe 2+ reacts with water to form insoluble ferrous hydroxide, Fe(OH) 2.If the condensate stream velocity is high enough, colloidal Fe(OH) 2 is swept into the water and car-ried downstream to deposit elsewhere. In low-flow areas of the condensate system, Fe(OH) 2 deposits near the
