Why choose
Fuel Oil Gas Through-flow Steam Boiler?
The new steam boiler is a single-drum longitudinal water-fire tube shell boiler with a moving grate as its combustion equipment. Radiant heating surfaces are formed by water-cooled walls on both sides of the furnace, with the two wings constituting the convection heating surface. Inside the boiler drum, threaded smoke tubes are arranged to form an additional convection heating surface. The furnace wall employs a new technique of integral pouring and ramming with heat-resistant concrete, and the outer side of the boiler main body is enveloped in a three-dimensional protective shell.
The boiler body's overall structure features a top-mounted drum with symmetrical arrangement of water-cooled wall tubes and header boxes on both sides. The barrel is welded together from the body and front and back tube plates. Inside the furnace, a spark-arresting wall is arranged to ensure high combustion efficiency. This series of boilers incorporates the latest scientific research results, such as arch-shaped tube plates and threaded smoke tubes, solving common problems like shell boiler tube plate cracks, water wall tube bursts, low thermal efficiency, insufficient output, and poor adaptability to coal quality.
The fuel enters the furnace through the moving grate to combust, generating flue gases that pass underneath the boiler drum and then through the exit flue windows on the arch wall into the convection tube bundles on both wings. The gases enter the threaded smoke tubes via the front smokebox and, after passing through an economizer and dust collector, are drawn by an induced draft fan and discharged into the atmosphere through the chimney.
