Introduction

The burner is fixed to the front wall of the boiler. After ejected by the burner, the fuel fires in micro positive pressure in the furnace (the first pass). High temperature smoke from the burning firstly turns 180° to the left at the end of the furnace, secondly enters convection tubes in the second pass towards the front of the furnace, thirdly turns 180° to the left and enters the economizer and condenser (the third pass) to fully transfer heat with fin tubes, and lastly enters the atmosphere. Water tube boiler is equipped with heating surface. High temperature smoke release heat out of tubes and water absorb heat inside of tubes. Water tube boiler is commonly used in hot water heating.
