Abstract
The utility model discloses a drum applied on boilers, of which the cross section is non-circular. The utility model solves the problems existing in northern saloon cars that the steel consumption of boilers is overlarge, pollution discharging points are not at the lowest points and tension bracing rods and fillet welds are both excessive. The utility model also solves the problems that the lower parts of smoke tube boilers and water and fire tube drums bulge, the water cooling degrees of hearths are overlarge, the intermediate heights of the hearths are over-low, the lower parts of the drums are easy to produce scale deposit and both sides of the hearths are dead angles for fume. The structure of the utility model can also be used on containers.
Description
The utility model belongs to a kind of drum of using on the boiler.
The boiler body transversal surface of the car boiler in the existing north is the door font, and the drum section of fire tube boiler and smoke tube boiler also is circular.And the utility model is non-circular drum (as shown).
Non-circular drum can replace car boiler door font boiler body under former prerequisite of exerting oneself with efficient, so just can fall lower steel consumption greatly, and the blowdown point is moved on to lowest part, significantly reduces stay bolt bar and fillet weld.Non-circular drum also can former exert oneself and the prerequisite of efficient under replace the circular drum of smoke tube boiler and fire tube boiler, so just can increase the burning of burner hearth intermediate altitude surface strengthening, reduce fractional cold in the stove and overheavy firing, cancel flue gas dead angle, burner hearth both sides and overheavy firing, avoid the easily fraud of long-pending scaling of drum bottom, make the blowdown point be arranged in both sides lowest part and the fraud of avoiding the easy bulge in drum bottom.
Non-circular drum is by several different curvature radius (R
1R
2R
3) the closed non-circular cylindrical shell that couples together, its flex point (being the point of connection of the different arc of different curvature radius) is located and external pressure arc position adjustable bracing bar and brace panel are strengthened.Its design, manufacturing, installation, operation and maintenance etc. are all undertaken by " steam boiler safety and technical supervision rules ", " hot water boiler safety and technical supervision rules " and boiler professional technique standard etc.
Accompanying drawing has provided one of the present utility model and has implemented the letter example.
