1. Based on picture, A. Classify the above boiler types based on technique combustion and the position of the water flow! B. Write a brief description of the 8 components in steam power plant system above! C. In addition to fuel, this power plant is also provided with limestone and sand. What is the purpose of the two kinds of income this compound?

Calculate the performance ratio, specific heat transfer area, specific flow rate of cooling water, conversion ratio, and salinity of brine blowdown for a single stage flash desalination unit operating at the following conditions: Feed salinity = 45000 ppm Feed temperature = 25 °C Heating steam temperature = 90 °C Production capacity = 1 kg/s Brine blowdown temperature = 35 °C - - - - - Top brine temperature = 80 °C Terminal temperature difference in the condenser = 3 °C Thermodynamic losses = 2 °C.

Chapter 6d BOOK: ENGINEERING THERMOFLUIDS, M. MASSOUD    Data: Total loss coefficient = 2.5m^2 Flow area = 0.5m^2 Total rate of decay heat of DSC = 15kW System thermal length = 3.5m Air temperature that enters the HSM = 22C   USE THE GIVEN DATA TO DETERMINE: 1. Temperature rise 2. Flow rate of air through the HSM 3. Total pressure drop from inlet to exit

(optional) Design a solar collector: Following the steps to decide the size of a solar collector. Step1: the customer wants to heat 500 liters of water from 15 to 80 C. How much heat is required? Step2: the local daily solar insolation rate is 1.13*107 J/m2. How much heat the solar can provide per m2? Step3: if 33% of solar energy can be used to heat water (q) with a solar collector, how much heat can be used to warm up cold water? Step4: what collector surface area is A (m2) required?
