Question 6 Natural gas is burned in a boiler furnace. The combustion of natural gas produces 1000 kW of heat. This heat is used to convert water into saturated steam in a boiler (which is a heat exchanger). Water enters the boiler as a liquid at 20°C and leaves as saturated steam at 20 bar (absolute) a) If only 75% of the heat generated in the furnace is transferred to the boiler, calculate the steam generation rate in the boiler...

Fuel is burned in a boiler to produce saturated steam at 10.0 bar absolute pressure from saturated liquid water at 10.0 bar absolute pressure. This H20 flows through tubes that run through the boiler, Energy released by combustion is transferred as heat through the walls of the tubes to convert the liquid water to steam at 10.0 bar. The fuel consists of 37 mol% ethane and 63 mol% acetylene, and is fed in the vapor phase at 50 °C and...

Figure 1 presents a seawater cooled steam ejector refrigeration/Heat Pump System for Naval Surface Ship Applications. A Steam Ejector Refrigeration System is thermally driven heating and cooling technology by changing the pressure to control the boiling temperature which will enhance evaporation of fluid to realize cooling purpose. A heat pump system is to utilize the phase change of fluids to realize heating and cooling purpose. Please answer following questions: exhaust gas boiler nozzle section...

answer a nd b with complete details
Boiler is a major equipment in the palm oil mill industry to provide steam for heating and power generation purpose. The source of raw water for boiler is pumped from a nearby river to the reserve pond for further internal and external treatment to remove all impurities, dissolved gases, and mineral content. Superheated steam generated from the boiler is used to run steam turbine for electricity generation and for heating process in the...

A steam power plant is intended to be used for heating as well as power generation. The net power required from this installation is 5 MW and the heating power is 12 MW. While the steam produced at 4 MPa, 440 degrees Celsius in the boiler expands in the isentropic turbine, the steam to be used in heating is drawn from the turbine at 140 kPa and it is condensed in the heating installation and mixed with water from the...

Thermo Final Exam open book open notes 2hrs 1. (10pts) A power plant can be described by an ideal Rankine cycle without any irreversibility's. he boiler produces superheated steam at a pressure of 200 bars and temperature of 600c (1). The steam expands adiabatically (and isentropicly) thru a turbine exiting as a saturated vapor/liquid mixture at pressure of 0.1bar (2). The mixture passes thru a condenser (P-0.1bar) until it is all saturated liquid (3). It is then pumped adiabatically to...

1. An industrial plant needs 20,000 lbm of saturated steam at 280°F per hour for heating purposes and ten MW of electrical power. A small turbine system is to be designed to handle both of these needs. Steam is supplied to a turbine at 400 psia pressure from a boiler and expanded until 280°F saturated steam is obtained whereupon the steam needed for heating is extracted. The rest of the steam is expanded in a second turbine to a condenser...

P8-29 A closed feedwater heater is used in a Rankine cycle Steam leaves the boiler at 20 MPa, 600°C. Between the high and low-pressure turbines, steam at 1 MPa is extracted and delivered to the closed feedwater heater. Feedwater exits the feedwater heater at 20 MPa and the saturation temperature of the 1-MPa steam; saturated liquid condensate is fed through a steam trap back to the condenser. Steam from the second- stage turbine enters the condenser at 10 kPa, and...

A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...

01: Steam enters the first turbine at 15.0 MPa and 600°C. The pressure in the condenser is 20.0 kPa. While some steam is extracted from the high-pressure turbine at 5 MPa and sent to the closed feedwater heater, the remaining steam is reheated to 600°C. The extracted steam is condensed as saturated liquid at 5.0 MPa and trapped to the open feedwater heater. Some steam is extracted from the lower-pressure turbine at 1.0 MPa and sent to the open feedwater...
