Corrosion and deposition in boilers, steam turbines and many types of process equipment are among the most expensive causes of outages in utility and industrial steam plants. Deposits and scale buildup on heat-transfer surfaces reduce efficiency, and when allowed to accumulate on steam turbines, such buildup can reduce the capacity. Corrosion-related failures can result in outages ranging from a few days...

Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...

Boilers generate steam using different methods to circulate the steam-water mixture through the evaporator tubes. These methods include natural circulation (Figures 1, 2a–2c), forced circulation (Figure 3a), and a once-through design. Figures 3b, 4 and 5 show examples of a waste-heat water tube and fire-tube boilers with external downcomers and risers. Most boiler systems have evaporator tubes heated...

Solid and serrated fins (Figure 1) are widely used as heat transfer surfaces in boilers and heaters. The use of finned tubes makes heat exchanger equipment compact. The fluegas pressure drop is also decreased relative to a comparable plain-tube design, resulting in lower operating costs. Fin geometry, such as fin density (fins/in.), fin height and fin thickness, should be selected with care as it impacts...

Supplying steam that meets process needs while protecting steam-system components, such as boilers and steam turbines (Figure 1), against scale, fouling and corrosion, requires purified feedwater (condensate plus makeup water). Depending on the steam pressure required, the specific approach of the water treatment may be shifted to account for a variety of issues. For example, caustic corrosion and...

The ASME Boiler and Pressure Vessel Code (ASME BPVC), which is administered by ASME (New York, N.Y.; www.asme.org; founded as the American Society of Mechanical Engineers), is a well-established standard for the design and fabrication of boilers and pressure vessels. ASME code-symbol stamps show compliance with the requirements of the standard, but code stamping of steam systems in ethylene and other large...

Today’s chemical processors must cope with rising labor costs, increasing global competition, escalating fuel costs and more-stringent safety and environmental regulations. To improve productivity and reduce costs in today’s competitive environment, many facilities are operating leaner than even before. And, downsizing strategies have seen the reduction of maintenance staff, which often results...

One of the most energy-intensive utilities for many facilities in the chemical process industries (CPI) is the steam system. Traditionally, steam-use optimization has centered on efficient heat transfer and eliminating waste [ 1]. Further optimization can involve a broader look at how steam supply and consumption interact dynamically throughout a large complex. This type of optimization often results in...

A well-operated steam generator can save money. In a steam-driven turbine system, water is heated in the steam generator to produce high-temperature, high-pressure steam. Steam is then expanded in a turbine to produce electricity from a generator. Turbine steam is condensed back into water in the condenser. A pump then returns the water to the steam generator. Engine thermodynamics Theoretically, the most...

Yesterday, U.S. District Court judge Paul Friedman denied a legal motion by the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) that would have prevented environmental groups from challenging EPA's stay of proposed changes to the Maximum Achievable Control Technology (MACT) standard for industrial boilers. While the decision was procedural, it suggests to ACC that the stay is...

Last year, the U.S. Environmental Protection Agency (EPA;Washington, D.C.; www.epa.gov) proposed new emissions standards for hazardous air pollutants (HAP) emitted by industrial boilers and solid-waste incinerators (CISWI) based on the performance of the maximum achievable control technology (MACT). The so-called “boiler MACT” final rules were signed by the EPA Administrator on February 21...
