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.

Sootblower and Boiler Cleaning Terminology, Principles and Applications

Deposits are removed from the corrugated heating surface by means similar to SCR catalyst cleaning applications such as straight-line sootblower. Swing arm sootblowers and dual media cleaning devices can also be used. Cleaning media must be aimed directly at the gas inlet face of the heating surface with relatively low velocities.

CO Boilers for the Hydrocarbon Processing Industry

Changes in FCCU catalyst and in process conditions have permitted reductions in the CO content of the gases leaving the unit. These changes also result in the gas temperature to the CO boiler increasing from the 1000F (538C) level to as high as 1450F (788C). New heat recovery boilers on FCC units are designed for these new process conditions.

A Primer on Steam Generation

The steam generator (boiler) evaporates water and supplies high temperature, high pressure steam, under carefully controlled conditions, to a turbine-generator set that produces electricity. The steam may also be reheated in the steam generator, after passing through part of a multi-stage turbine system, by running the exhaust steam back to the boiler convection pass.

Nitrogen Oxides (NOx) Primer

SNCR typically is limited to lower NOx reduction levels but may be the more economical choice depending on the required NOx reduction or the unique project requirements. Both technologies have been successfully applied for NOx reduction on multiple fuels and boiler types.

The Importance of Construction Technology

Technological advances including computer-aided design, global positioning systems, laser scanning systems, and more powerful lift cranes have enabled construction engineers and technicians to support supervision by refining the planning process and expediting the work in the field.

Ash Handling Terminology and Primer

Bottom ash is most commonly conveyed in a hydraulic system in which the ash is entrained in a high flow, circulating water system and delivered to either an ash pond or to a remote dewatering device. Alternatively, mechanical drag systems have been used to convey bottom ash to the dewatering storage bin because they use less water and usually have a lower initial cost.

Effect of Operating Variables on Fuel Ash Corrosion in Boilers

Sootblowers are the primary means of dealing directly with furnace wall slagging and convection pass fouling. The most important fundamental requirement is to use this equipment in a preventive, rather than corrective, manner. Sootblowers are most effective in controlling dry, loosely bonded deposits that typically occur in the early stages of deposition.

Numerical Modeling in Power Plant Applications - An Overview

Continuous and steady advances in computer technology have changed the way engineering design and analyses are performed. These advances allow engineers to manage larger-scale problems and more complex systems, or to look in more detail at a specific process. Using advanced computer technology to perform engineering analysis, numerical modeling has emerged as an important field in engineering.

Finding the Root Cause of Boiler Tube Failures

Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. A comprehensive assessment is the most effective method of determining the root cause of a failure. A tube failure is usually a symptom of other problems.

Part II - General bid evaluation

A thorough review must consider whether the supplier has offered the intended scope, and any exceptions to the specification must be evaluated. Bid evaluation generally includes a review of scope, operating ease, maintenance and operating costs, service, design features and hardware, construction features, schedule, project management and project team expertise, experience, commercial terms, and price.
