Why the Velox boiler did not become a fleet standard

Velox boiler trials are recalled as exposing excessive complexity and poor power density once the system's space demands inside a hull were considered.

Question

Why did the Royal Navy not adopt the Velox boiler after testing it?

Short answer

The remembered objections are complexity, large space demands, and disappointing practical power density.

Notes

Complexity and poor power density are the recalled reasons for the Royal Navy's decision against wider use of the Velox boiler. The Navy did test the system. Although it promised high output, it occupied considerable space inside the hull. That combination made the practical installation less attractive, though the explanation is offered from memory without detailed trial figures.
