Description

The fully automatic secondary burning boiler

The utility model relates to boiler, particularly a kind of fully automatic secondary burning boiler.

Conventional utility boiler is disposable burning heating at present, combustor is installed in furnace bottom, the stove hall is a fire tube on the top, and flare promptly directly goes out from smoke stack emission through water pipe, and it is insufficient to burn like this, the thermal efficiency is low, produce defectives such as steam time length, also useful recently combustor is from the fire tube heating of the downward stove hall of furnace roof, and perforate is connected and installed auxiliary fire tube above the inner bag sidewall simultaneously, to bottom and from side dress chimney, the chimney periphery has the waste heat recovery of water logging bubble to waste gas from auxiliary tube row.The sufficient combustion situation take a favorable turn like this, and the thermal efficiency is improved, and toxic emission is low.But complex structure; cost height, boiler rinsing will be opened the closedtop lid, allow the people enter to wash; combustor shove charge top; maintenance is difficulty very, and burning stops when shutting down, and remains fiery interior heat amount to rush at; high concentration is at the combustor mouth; the temperature height causes the combustor parts to damage, and rushes at the burning cover in smog and the fire and crosses electric eye, for the second time with machine burning difficulty.

The purpose of this utility model be to provide a kind of fire tube of body of heater inner bag be tiltedly discharging be beneficial to oil smoke and waste material slippage sticking the staying that do not stagnate, limit, fireplace side, fire tube limit install combustion machine, inner bag closedtop lid is the circular arc capping, only pass to chimney to open an aperture ventilation combustion-supporting in the centre, the inner bag bottom is the fire tube by rows that tiltedly discharges, inner bag is equipped with smoke pipe to increasing between the outer courage, smoke pipe top mouth passes to chimney, simple and reasonable, easy to manufacture, easy to install, thermal efficiency height, toxic emission is few, and noise is low, safe and reliable fully automatic secondary burning boiler.

Technical solution of the present utility model is such.Comprise by body of heater, inner bag, outer courage, combustor, manhole cover, hand hole device, go up petticoat pipe, following petticoat pipe, fire tube, smoke pipe, last petticoat pipe is a body of heater between the petticoat pipe extremely down, be that flat tube sheet is affixed with outer courage above the body of heater, outer courage bottom and upper segment is equipped with the hand hole device, outer courage also is equipped with manhole seat, manhole cover.Outer courage middle part dress combustor, combustor is by outer courage inner bag, and inner bag communicates with Lu Tang, open aperture dress stay bolt pipe in the middle of the inner bag closedtop lid, and go out to chimney from flat tube sheet, the stove hall below of inner bag is the fire tube of adorning crosswise, inner bag is to being water interlayer between the outer courage, fire tube communicates with water interlayer, following petticoat pipe and U-shaped pin circle Joint, elbow is equipped with in middle perforate at the bottom of the following petticoat pipe, and elbow is hinged with the explosion proof door body outward, explosion proof door body dress cover plate, hinge, explosion stack.Perforate dress blowdown bend pipe at the bottom of the U-shaped pin circle, dress long-neck Pressure gauge joint chair between the last petticoat pipe peace tube sheet, long-neck stop valve joint chair, dress chimney in the middle of the end face of last petticoat pipe.

The utility model has the advantages that simple and reasonable; reasonable in design, easy to manufacture, install simple; easy to maintenance; running noises is low, and simple to operate easy, cost is low; it is fast to fire boiling water hot water; went out steam in 10 minutes continuously, thermal efficiency height, toxic emission is low; be suitable for life, industrial application boiler feedwater; steam supply, operation is full-automatic, and combustor is installed in the boiler intermediate combustion; during shutdown; after-heat unloads heat pipe and discharges from the centre, do not influence combustor, or temperature is crossed and exceeded the damage that causes combustor when concentrating heat.
