Combined Heat and Power for the CPI: Modern Concepts

The continuing development of natural gas extraction from shale deposits, known simply as shale gas, is fueling the growth of simple- and combined-cycle power plants. Much coal-fired power is being replaced by these technologies. In addition, though, simple- and combined-cycle…

Use this light for boiler inspections

Larson Electronics The recently launched WALBL-2 x 1000WMH Boiler Light is a telescoping light tower with a folding boom that is designed to allow versatile deployment and high-output illumination. The light features a right-angle extension arm, wheeled base, and a…

A furnace system for processing carbon fibers

The carbon-fiber pilot line consists of an oxidation furnace, carbonization furnace and a graphitization furnace, The four-zone oxidation furnace operates at 325°C for stabilizing precursor fibers, and has a connecting two-step system for carbonization and graphitization at the required temperatures…

A clean steam separator for pristene processing

The CS10 Clean Steam Separator with enhanced surface finish has been engineered to overcome problems associated with wet steam and ensures the correct quality of steam is supplied to the point of use, thereby preventing damage to control valves and…

Freeze food faster with this new impingement freezer

The HVF-Freezer (high-velocity freezer) is said to be an improved freezer concept based on existing impingement-freezer technology. The new HVF uses high-velocity air jets to quickly reduce the outer layer temperature of food by breaking the insulating boundary layer, allowing…

Five Steps to Replacing Aged Heat-Transfer Fluid

Changing out used heat-transfer fluid is critical to the efficiency of a heat-transfer fluid system. A well-operated heat-transfer-fluid system can enable efficient production, fewer shut-downs, less maintenance time and lower costs. In order to maintain a sound heat-transfer system, it…

Steam-System Water Preparation

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…

Waste Heat Recovery Methods And Technologies

Waste heat recovery (WHR) is essential for increasing energy efficiency in the chemical process industries (CPI). Presently, there are many WHR methods and technologies at various stages of implementation in petroleum refineries, petrochemical, chemical and other industry sectors. Increasing energy…

Applying ASME Boiler Code to Steam Generation Systems

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.…

Rotary tube furnaces for temperature up to 650°C

This company is introducing two new rotary tube furnaces that are suitable for heat treatment; calcination of powders, granules and fibers; pyrolysis; and the recycling and production of rare-earth metals. The FDHK-5-1400/10800/450 model operates at a maximum temperature of 550°C,…
