Specifications

The Viessmann 7830016 Viessman Combustion Chbr.Rear Refractory is described as a Non-Combustible, Ceramic Heat Plate designed as a Burner target for boiler. It specifically fits models in the WBxB/B2xA series, rated for 68-125 MBH. The material itself, ceramic, is key here as it can withstand the extreme temperatures generated during combustion without degrading or contributing to the burning process.

This specification is vital because the rear refractory acts as a heat shield and also directs the flame from the burner, ensuring optimal fuel-air mixture and efficient heat transfer. A failing refractory can lead to incomplete combustion, wasted energy, and potential damage to other boiler components. Its designation for specific boiler models like the WBxB/B2xA series means it’s engineered for a precise fit, crucial for sealing the combustion chamber effectively.

Compared to older, more porous refractory materials, this ceramic version likely offers better thermal insulation and a longer lifespan. Its design as a burner target means it helps concentrate the heat precisely where it’s needed, maximizing boiler efficiency. The MBH rating (thousand British Thermal Units per hour) indicates the boiler’s capacity, and this refractory is designed to handle the thermal load within that range.
