Babcock & Wilcox Vølund AB products

Our extensive worldwide experience in designing, manufacturing, installing and servicing more than 700 RB boilers gives our customers the reliability and dependability they demand. B&W`s RB boiler incorporates natural circulation which takes advantage of the density difference between water in the downcomers and the steam/water mixture in the furnace tubes. With natural circulation, no pumps are required, so auxiliary power requirements are reduced and availability is improved. B&W`s RB boiler is typically designed with a parallel back-end that allows gas biasing reheat steam temperature control.

Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. In addition, load-following capabilities are attainable with B&W’s in-bed heat exchanger technology.

The DynaGrate combustion grate is one of the world`s most advanced combustion grates for waste-to-energy applications. The DynaGrate provides excellent performance with low maintenance costs due to a design technology that causes little wear. With the DynaGrate technology we can meet tomorrow`s demands for waste-fired plants, which require a high level of accessibility, fuel flexibility, and energy recovery, under environmentally sound conditions.

Combustion grates provide waste flow that ensures drying, ignition, combustion, energy release and complete burn-out before the bottom ash outlet.

Provides a continual and even fuel layer across the entire combustion grate for steady energy output and maximum efficiency. It is tolerant and robust with design features that allow servicing during operations.

With mechanical design features for high availability, fewer unplanned stops and safe service access. The DynaDischarger ash extractor is compatible with any grate, regardless of manufacturer. It can be retrofitted during a normal service shutdown period.

B&W`s single-drum recovery boiler, now the standard in the pulp and paper industry, provides high availability with safe operation and low maintenance. We have been at the forefront of technologies which improve boiler and cycle efficiency, such as firing higher solids concentration liquors, using low pressure steam to heat combustion air, and feedwater heating. Existing units can take advantage of these advanced designs and features through our range of pulp mill recovery and power boiler upgrades.

With an experience base of more than 200 BFB units worldwide, B&W’s BFB boilers are helping the world realize the promise of clean energy from a wide variety of fuels.

Götaverken Miljö has installed a great number of heat pumps over the years. Our early references include some of the largest turbo compressor heat pumps in the world (at Ryaverket in Gothenburg). We have installed both compressor and absorption heat pumps connected to the flue gas cleaning systems at waste incineration plants. In recent years absorption heat pumps connected to flue gas condensation systems at waste incineration plants have attracted the greatest attention, since such installations often considerably increase the potential for substantial energy recovery and revenues.
