BOILER DESIGN CONSIDERATIONS Operational Definition The essential requirement to the boiler design is a thorough understanding of the specific cycling duty of the system. The thermal and mechanical design of any practical boiler design is possible when a clear and concise definition of the operational characteristics is known.

The volumetric composition of a sample of gases fuel is the following: H 2 = 50%, CH 4 = 20%, C 2 H 4 = 2%, CO 2 = 5%, CO = 16%, N 2 = 7% 1. Determine the molecular weight and the density of the mixture oat STP (15 C & 1 atm) if the total pressure is 1 atm. 2. Determine also the gravimetric composition or composition by weight
The various heat transfer sections of a boiler can be grouped as follows : Utility Industrial Furnace Furnace Superheater Superheater Reheater —— ——— Boiler Bank Economiser Economiser Airlheater Airheater The design aspects of these sections are discussed further. 2. FURNACE The furnace design is influenced by the following factors: i) Fuel
