B&W's supercritical and ultra-supercritical boiler designs offer the flexibility and reliability to meet the most demanding steam generation needs of our customers. At supercritical pressures, steam turbine efficiency improves significantly compared to the typical subcritical cycle.

DESIGN CONSIDERATIONS In the designing of the exchanger following factors were put to consideration. 1. The exchanger surface has to be the most efficient and suitable for gas-gas heat exchange. 2. The design has to consider the fouling effect of the flue gases. 3. Get a quote. Industrial Boiler Chimneys - lodgings-hamburg.de. design considerations of chimney of industrial boilers. …

· PDF fileFire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

· PDF fileThe Claus Waste Heat Boiler (WHB) is a critical piece of equipment in a Sulphur Recovery Unit (SRU); its fundamental purpose is as a heat transfer device used in energy recovery. Sulphur plant operators have recently been experiencing higher than normal WHB failure rates, perhaps from oxygen enrichment and pushing rates. The WHB has become the weak link in the SRU; consequently, increased attention …

01-05-2020· The mustard-colored lines under the steam latent heat line are most important because they demonstrate the reduction in latent heat for a given percentage of wetness — up to a 15% wet steam mixture. Some applications may have a wet steam slurry of 30% condensate, so 15% wet steam is a real possibility to be considered, particularly at the “wet end” of a plant. The brown line represents …

The furnace is the most important part of a boiler. Its primary function is to provide adequate space for fuel particles to burn completely and to cool the flue gas to a temperature at which the convective heating surfaces can be operated safely. How this can be done depends on the type of firing method employed. For example, in the case of stoker fired boilers, the combustion takes place mostly on the grate. Here …
