Horizontal Style and Industrial Usage Fire tube chain grate coal fired hot water boiler

 1. Introduction of Horizontal Style and Industrial Usage Fire tube chain grate coal fired 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 Horizontal Style and Industrial Usage Fire tube chain grate coal fired 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

Function:choose the best furnace among tens of programs.

Purpose:improve the economy.
