You are the design engineer for a natural gas co-generation power facility shown in the diagram below. You have been asked if the facility's exhaust gas can be fed to a greenhouse in order to grow plants without having to add a make up stream of air to cool it. This can be done if the temperature of the facility's exhaust gas is less than 130°F (54.4°C) In steady state, the Gas engine is fed a stream of natural gas...
A fuel gas containing 85.0 mole% methane and the balance ethane is burned completely with 15.0 % excess air. The stack gas leaves the furnace at 900.0 °C and is cooled to 450.0 °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. Physical Property Tables Combustion Gases Correct. Take as a basis 100.0 mol of the fuel gas fed...
Consider the following combustion reaction of butane (C4H10): 13 C.H. + -0, 400, +5H,0 2 a) Case I: 25 kmol/h of C4H10 and 1750 kmol/h of air is fed to the reactor. Determine the percentage excess air used. You may assume that the air contains 21% oxygen (O2) and 79% nitrogen (N2) (on a mole basis). [15 marks] b) Case II: 125 kmol/h of C4H10 and oxygen (O2) is fed to the reactor. The product stream leaving the reactor contains...

Problem 11.051 Exhaust gas from a furnace is used to preheat the combustion air supplied to the furnace burners. The gas, which has a flow rate of 15 kg/s and an inlet temperature of 1100 K, passes through a bundle of tubes, while the air, which has a flow rate of 10 kg/s and an inlet temperature of 300 K, is in cross flow over the tubes. The tubes are unfinned, and the overall heat transfer coefficient is 90 W/m2...
A bituminous coal is burned with air in a boiler furnace. The coal is fed at a rate of 40000 kg/h and has an ultimate analysis of 76wt% C, 5wt% H, 8wt% O, negligible amounts of N and S, and 11wt% non-combustible ash. Air enters a preheater at 30 °C and 1 atm with a relative humidity of 30%, exchanges heat with the hot flue gas leaving the furnace and air enters the furnace at temperature Ta (°C). The flue...

Acid rain results from the reaction of nitrogen dioxide with water in the air. Unbalanced equation: NO2(g) + H2O(l) --> HNO3(aq) + NO(g) A water spray is sometimes used in exhaust stacks at coal fired power plants to help prevent acid rain. Given the following parameters, calculate the concentration of the nitric acid in 8L of wastewater (assume no evaporation ... I know this is not reality but let's make the calculation a bit easier!). 1000L/min vented through the exhaust...
