The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
Steam Rankine cycle is known as one of the main power-generating cycles, which consists of four key devices, namely a boiler (heat exchanger), a steam turbine, a condenser (heat exchanger), and a pump, as illustrated in Fig. 28.This cycle needs heat input for the boiler either by burning fossil fuels, such as oil, coal, and natural gas, or by obtaining the necessary heat from renewable energy

Determine (a) the thermal efficiency, (b) the back work ratio, (c) the heat transfer to the working fluid per unit mass passing through the boiler in kJ
Factor of Evaporation Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu.
e. mass flow rate of the condenser cooling water, in kg/h, if cooling water enters the condenser at 15°C and exits as 35°C. Discuss the effects on the vapor cycle of irreversibilities within the turbine and pump. 5/7/2012 8:47 AM Dr. Mohammad Abuhaiba, PE 19
A coal-fired boiler produces superheated steam steadily at 1 MPa, 500 o C from the feed water which enters the boiler at 1 MPa, 50 o C. For a mass flow rate of 10 kg/s, determine (a) the rate of heat transfer from the boiler to the water. Oil with a density of 800 kg/m 3 is pumped from a pressure of 0.6 bar to a pressure of 1.4 bar, and the
MCQ in Power Plant Engineering Part 2 | ME Board Exam
Aug 16, 2019 · A coal fired steam plant takes in feed water at a temperature of 70°C and produces 15 tonnes of steam per hour at a pressure of 60 bar and temperature 400°C. The fuel consumption rate is 1.5 tonnes per hour and the calorific value of the fuel is 40MJkgˉ¹. Determine the power rating of the boiler
Q: Two boilers of 8 bar and 6 bar are being connected to the same storage tank. A person is saying that 8 bar pressure steam will repel 6 bar steam and the pipeline of 6 bar will be filled with 8 bar, is it true? No it is not true. This hypothetic
The Challengers were designed for fast freight service, but occasionally pulled passenger trains. No. 3985 originally burned coal and pulled a tender with a 32-ton capacity. In 1990, it was converted to use No. 5 oil. The top speed of No. 3985 is about 70 miles an hour.

The Airbus A400M Atlas is a European four-engine turboprop military transport aircraft.It was designed by Airbus Military (now Airbus Defence and Space) as a tactical airlifter with strategic capabilities to replace older transport aircraft, such as the Transall C-160 and the Lockheed C-130 Hercules. The A400M is between the C-130 and the Boeing C-17 in size; it can carry heavier loads than
Water is the working fluid in a Carnot vapor power cycle. Saturated liquid enters the boiler at a pressure of 100 bar, and saturated vapor enters the turbine. The condenser pressure is 0.06 bar.
