0.7MW/1.4mw/2.8mw/4.2mw/5.6mw Coal fired single drum 95 degree output hot water boiler
1.Introduction of 0.7MW/1.4mw/2.8mw/4.2mw/5.6mw Coal fired single drum 95 degree output hot water boiler
It is a kind of one-drum, horizontal, three pass, water-fire tube boiler. This series adopt lots of new technology, such as use convex tube plate, wing-shape flue, spirally corrugated tube and so on. The water tubes in the two sides of the furnace is radiation heating surface, and the wing-shape flue and spirally corrugated tube are convection heating surface.

4. Advantages of 0.7MW/1.4mw/2.8mw/4.2mw/5.6mw Coal fired single drum 95 degree output hot water boiler
1)Spirally corrugated tube
Function:enhance the heat transfer, obviously reduce quantity of tubes and size of boiler shell.
Purpose:save steel and avoid fouling; increase flexibility and prevent cracking of tube plate.
2)Wing-shape flue
Function:reduce smoke temperature of high-temperature tube plate to slow down subcooled boiling.
Purpose:reduce heat load of boiler bottom to prevent cracking and bulge of tube plate
3)Convex tube plate
Function:increase flexibility of tube plate to reduce thermal stress in weld of tube end
Purpose:prevent cracking of tube plate;cancel tension brace piece;simplify the structure.
4) Backwater lead to high temperature tube plate
Function: improve water flow speed on high temperature tube plate, avoiding subcooled boiling.
Purpose:prevent cracking of tube plate
5) Simple circulation loop, big size down pipe and bottom container.
Function: increase the flow speed of water pipe to avoid subcooled boiling.
Purpose:prevent the explosion of pipe and increase the reliability of water circulation.
6) Injection tube
Function: increase the flow speed of water pipe to avoid subcooled boiling.
Purpose:prevent the explosion of pipe and increase the reliability of water circulation.
7). Smoke separation room
Function:separate smoke by inertia
Purpose:reduce original concentration of smoke emission
8).Self support
Function: Cancel steel frame
Purpose: save steel
9).new type arch
Function:enhance burning and high adaptability of coal
Purpose: Improve burning efficiency
10).Optimally designed CAD
