In a palm oil processing plant, the crude oil is heated using hot water from a furnace. The furnace burns oil palm biomass to heat water (initial water temperature of 18*'C). After the hot water was used to heat the crude palm oil, the hot water (cp = 4180 J/kg. °C) was then discharged to the drain at a rate of 7 kg/min at a temperature of 70°c. The funace has an efficiency of 82% and operates for 9 hours a day, 6 days a week, and 48 weeks in a year. The cost for 1 tonne of oil palm biomass is RM 18 (1 tonne = 105,500 kJ). Hence, the mill engineer intends to install heat exchangers to save on operating costs. This heat exchanger will use the hot water discharged into the drain earlier to pre-heat the new water before entering the furnace as shown in Figure 4. However, only 75% of the heat from the previously discharged water can be used. Determine: a) Heat transfer rate for heat exchangers c) The total annual cost that can be saved by using heat exchangers.

Biomass is used as fuel to power the following cogeneration plant on a school. The turbine drives an electric generator to produce electricity, and part of the steam is extracted to provide heating to campus buildings. The boiler provides 106 kg/h of steam at 6 MPa, 520 °C, of which 4x105 kg/h is extracted between the first and second turbine stages at 1 MPa and diverted to the building heating load. Condensate returns from the building heating load at 0.95 MPa, 115 °C, and it is mixed with liquid exiting the lower pressure pump at 0.95 MPa. The entire flow is then pumped to the boiler pressure. Saturated liquid at 6 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 89 and 85%, respectively. The efficiency of the electric generator is 93% for converting turbine mechanical power into electricity. Calculate the heating load in kJ/h. Calculate the electric power generated in MWe.

A portion of the cooling surface is screened from the incoming steam and the air is passes over these screened tubes to the air extraction and becomes cooled below the condensate temperature. The condenser receives 20 000kg/hr of dry saturated steam at 36.2°C. At the condensate outlet the temperature is 34.6°C TK and at the air extraction the temperature is 29°C.
