Abstract
A symmetrical indent water-cold boiler fire chamber is an improvement of the original boiler fire chamber. The water-cold wall tube of the original boiler is arranged on the cross-section of the fire chamber in a rectangle, resulted in small radiation heating surface, poor heat transferring effect, long fire chamber and high cost. The utility model arranges the water-cold wall tube in the fire chamber along the both sides of the fire chamber and vertical to the cross-section of the fire chamber in a symmetrical indent, and the tube spacing is small, having functions of big ejecting force, high efficiency, compact conformation and low cost of manufacture.
Description
The utility model relates to a kind of universal machine Industrial Boiler burner hearth, particularly a kind of symmetrical zigzag water-cooling wall boiler furnace.
Existing Industrial Boiler has two types: a kind of is the longitudinal boiler that drum is vertically arranged, another kind is the pressure-bearing type boiler of drum lateral arrangement, the water-cooling wall pipe of burner hearth of these two kinds of boilers is rectangular arrangement on the burner hearth cross section, promptly linear is arranged, sees Fig. 1.This layout radiation heating-surface is little, and flue gas, air can not fully mix, and needs secondary air, having increased equipment, leaks out unavoidably in the burner hearth both sides, and leaked-in air and flue gas are taken their own roads, reduced heat-transfer effect, under the situation of identical radiation heating-surface, rectangular arrangement, burner hearth is long, and boiler body metallic steel consumption is big, simultaneously, the pipe distance of this layout heating surface is generally greater than the design recommendation, make boiler volume big once more, the metallic steel consumption is high, the manufacturing cost height.
The purpose of this utility model provides a kind of symmetrical zigzag water-cooling wall boiler furnace, and it has the heat transfer efficiency height, compact conformation, advantage such as volume is little, and is in light weight, cheap for manufacturing cost.
The utility model is to constitute like this: the water screen tube 1 in the burner hearth is arranged vertically along burner hearth 3 both sides and burner hearth 3 cross sections and is symmetrical zigzag, the corresponding layout of shape that the cross section inner wall shape of burner hearth 3 both sides heat-insulation layers 2 and water screen tube 1 are arranged at burner hearth 3 both sides cross sections is symmetrical zigzag, the pipe of water screen tube 1 is 76.5m/m～102m/m apart from S, and is 1.5～2 times of caliber.
Further specify the utility model below in conjunction with accompanying drawing.Fig. 1 is existing boiler furnace cross section view.Fig. 2 is the utility model cross section view.In the utility model, water screen tube 1 is contained in the burner hearth both sides and is arranged vertically into symmetrical zigzag with the burner hearth cross section, heat-insulation layer 2 is in the outside of burner hearth both sides, and the shape that its cross section inner wall shape and water screen tube 1 are arranged at burner hearth 3 both sides cross sections is corresponding to be symmetrical zigzag.
For the water-cooling wall pipe of burner hearth 1 of 6 tons of water-tube boilers, adopt φ 51 * 3m/m20
#Carbon steel tubing, burner hearth heat-insulation layer 2 adopts the refractory brick material, and the pipe distance of water screen tube is 80m/m.
Claims (2)
1, a kind of symmetrical zigzag water-cooling wall boiler furnace, comprise water screen tube 1 and heat-insulation layer 2, it is characterized in that water screen tube 1 is vertical with the burner hearth cross section along burner hearth 3 both sides is symmetrical zigzag and arranges, the shape that the cross section inner wall shape of burner hearth 3 both sides heat-insulation layers 2 and water screen tube 1 are arranged at burner hearth both sides cross section is corresponding to be symmetrical zigzag.
2, water screen tube boiler furnace according to claim 1 is characterized in that: the pipe of water screen tube 1 is that 76.5m/m～102m/m is 1.5～2 times of caliber apart from S.
