Construction Planning and Scheduling

Typical participants include the project manager, scheduler/planner, project superintendent(s), construction engineer(s), and other contributors as selected by the project manager. The basis for this planning session is the scope of work as originally defined and estimated, and the existing conditions of the construction site.

Part I - Specifying a Steam Generator

The basic design is derived from the functional requirements of the application. The equipment designer needs to know the key characteristics of all major system inputs and all performance output requirements. This information is essential for setting vital system design parameters such as size, capacity, materials, equipment redundancy level, etc.

Boiler Operations That Affect Efficiency (Part 2)

Adjustments can typically vary the turbulence and flow rates in burners. Increased turbulence increases the air-fuel mixing. It also increases the combustion intensity, provides faster heat release, reduces unburned carbon (UBC) in the ash, permits operation with less excess air, and increases boiler efficiency.
