SPLASHING ASH ADHESION PREVENTING TYPE FIRE TUBE BOILER

摘要

PURPOSE: A fire tube boiler prevents foreign matter from adhering on the inside of a fire tube or an inlet to postpone boiler cleaning and makes the flow of combustion gas to improve efficiency thereof. CONSTITUTION: Inlets(31) of fire pipes(30) connecting a wing room(20) with a heat collecting room(40) and the heat collecting room(40) with a smoke exhausting room(50) are circumscribed with each other. The area between the inlets(31) is minimized as the inlets(31) are connected with the inner sides of the fire tubes(30) with gentle slopes. Splashing ash does not block the fire pipes(30) as a wall of the fire tubes(30) built toward the inlets(31) of a usual boiler is not needed.
