Shuttle kiln burners

A row of pulse-fired, low NOx burners with preheated air, like what will be supplied on the shuttle kiln for this project.

Riedhammer GmbH recently secured two orders from a leading manufacturer of green energy products: A rotary calciner to produce the raw materials and a high temperature batch kiln to sinter those materials into ceramic electrolytes. Both will be operational in the second quarter of 2011. Both of the kilns will be installed at an existing facility that is being repurposed to produce green energy products.

The batch kiln has an internal volume of 12 cubic meters (425 cu. ft.) and fires to 1600°C (2900°F) using natural gas as a fuel. It includes the latest technologies for reduced emissions, energy recovery, and high volume production, while maximizing temperature uniformity and minimizing potential contaminants.

The rotary calciner can process more than 500 kg/hr (1,100 lb/hr) of the raw material. The tube is lined with special, high-purity materials to minimize silica, alkali and transition metal poisoning of the material. The calciner is direct-fired using natural gas.

Riedhammer’s experience, responsiveness and ability to meet the customer’s budget goals without sacrificing quality were the reasons cited by the customer for selecting Riedhammer as the supplier for this equipment. The total value of these two projects is more than US$ 5.3 million.

Riedhammer, based in Nuremberg, Germany has supplied hundreds of kilns for the manufacture of a diverse array of electronic ceramic components including advanced batteries, fuel cells, passive components and sensors. In addition to batch kilns, Riedhammer supplies tunnel, roller, pusher-slab and rotary kilns that may be fuel-fired or electrically heated in sizes from bench-top through to the largest custom-engineered kilns ever delivered. Riedhammer is a part of The Sacmi Group (, manufacturing machines and complete plants for the Ceramics, Beverage & Packaging, Processing and Plastics industries.

RHFL 17125 and RHFL17027: New small high-temperature furnaces from Riedhammer ready to work for you.

RHFL 17125 and RHFL17027: New small high-temperature furnaces from Riedhammer ready to work for you.

Riedhammer GmbH introduces today their RHFL and RHBL small furnace lines. These are fiber-lined, electrically heated, standardized furnace designs that can be delivered quickly and economically for the development and production of technical ceramics.

Both lines are available for use to maximum temperatures of 1700 or 1800°C (3090 or 3270°F) in sizes from 27 to 250 liters (1 to 9 cubic feet). The RHFL is an economical front-loading design, while the RHBL is a bottom-loader designed for optimal temperature uniformity and ergonomics. Each unit can be customized by selecting from an array of standard options.

“Today’s technical ceramics are about two things,” says Hartmut Weber, Riedhammer’s Marketing Director, “small and fast. The RHFL and RHBL are our products that answer these needs. All of the furnaces feature a unitized design, with integrated power and temperature controls in one compact frame. These units can be in production hours after delivery.”

The RHFL and RHBL compliment the larger, custom-made kilns and furnaces Riedhammer has been supplying to the ceramics industry since 1919. These include elevator, shuttle, roller-hearth, pusher-plate and tunnel kilns. Thousands of Riedhammer kilns are installed throughout the world making advanced ceramic products such as batteries, fuel cells, emission control devices, electronic ceramics, and ceramic membranes.

As part of “Team by Sacmi,” Riedhammer – with its partners Alpha Ceramics, Laeis, and SAMA, – offers manufacturers of ceramics and advanced materials end-to-end solutions for the development, optimization, and production of their products.
