Evolution of wood boilers

摘要

Almost 40 years ago when my company Stadler Corporation introduced one of the first residential European wood boilers to New England, they were elementary in design and in their infancy of wood burning know-how. Today's boilers are true marvels of wood burning technology. Nowadays combustion efficiencies exceed 90% with clean, zero visible smoke discharge at the flue stack. They have built in microprocessors that control combustion air intake to optimize combustion and emission levels, and boiler return water temperature, plus, manage buffer storage tank loading and unloading, as well as system consumer valves.
