Abstract
The utility model discloses a vertical shaft type biomass combustion boiler with hearth temperature being adjustable. The vertical shaft type biomass combustion boiler comprises an upper drum (1), a lower drum (2), a hearth (3) and two-stage economizers (4), wherein the upper drum (1) is communicated with the lower drum (2) by densely arranged convection tube banks (10); water wall tubes (8) are densely distributed on a right side wall and a left side wall of the upper part of the hearth (3); microburst soot blowers (5) are arranged on a side wall of the boiler, on the right and left sides of the convection tube banks (4); a microburst soot blower (5) is also arranged between the two-stage economizers (4); a combustion chamber (6) is arranged in the middle of the hearth (3); cooling water tubes (9) are densely distributed on a right side wall and a left side wall of the combustion chamber (6); and a biomass fuel ejecting port (7) is formed on a rear side wall of the combustion chamber (6). The boiler effectively solves the problems that the life and stable operation of the boiler are affected due to the insufficient steam output and excessive hearth temperature arising from unsmooth smoke flow.
Description
Technical field
The utility model relates to water-tube boiler, specifically, is the biomass fired boiler of a kind of pair of drum.
Background technology
As shown in Figure 3 be with chain fire-gate double-drum boiler, with living beings or the coal source that acts as a fuel.The place ahead of this boiler is provided with coal bunker 13, and the coal outlet of coal bunker 13 links to each other with the traveling-grate stoker 14 that is arranged on burner hearth 3 belows, by traveling-grate stoker 14 and air blast coal is sent into burner hearth 3 internal combustion; The middle part of burner hearth 3 is the combustion chamber, and the sidewall in the combustion chamber has the biomass fuel entrance, and the biomass fuels such as stalk spray in the combustion chamber by the biomass fuel entrance.This boiler has burning coal and two kinds of functions of living beings concurrently, and cost is low, engineering reliability is high, realizes the recycling of novel energy, turns waste into wealth.
Between the afterbody of boiler, two-stage economizer 4, be provided with steam sootblower 12, when using coal fuel, can satisfy the demand, the phenomenon of flue gas ash with boiler sootblowing steam felt jam exhaust gases passes just appearred when using biomass fuel, boiler to blow grey effect bad, affect dust removing effects, cause steam production to descend, maintenance period lengthens.
In addition, only be provided with water screen tube 8 on burner hearth 3 tops, in use find, the burner hearth 3 temperature especially temperature of combustion chamber, burner hearth 3 middle part are still too high, affect the service life of boiler and safety, the stable operation of boiler.
The utility model content
The steam production that the utility model causes because flue gas is obstructed for boiler is not enough, fire box temperature is too high affects boiler life and stable operation two aspects are improved.
For this reason, the technical scheme that the utility model adopts is: the vertical shaft type biomass fired boiler that a kind of fire box temperature is adjustable, comprise upper drum, lower drum, burner hearth and two-stage economizer, described upper drum and lower drum are horizontally disposed, and lower drum is shorter than upper drum, described burner hearth is positioned at the below of upper drum, the top of burner hearth extends to the place ahead of lower drum, convection bank by intensive layout between described upper drum and the lower drum communicates, the left side of described upper furnace, be densely covered with water screen tube on the right side wall, key is: described convection bank is left, be provided with microexplosion formula soot blower on the boiler side walls of right both sides, between the two-stage economizer, also be provided with microexplosion formula soot blower; Described burner hearth middle part is the combustion chamber, and the left and right sidewall in described combustion chamber is densely covered with cooling water pipe, has the biomass fuel jet on the rear wall of described combustion chamber.
Respectively be provided with 3 microexplosion formula soot blowers on the boiler side walls of described convection bank arranged on left and right sides, and each microexplosion formula soot blower horizontal interval setting, be provided with a microexplosion formula soot blower between the described two-stage economizer; The microexplosion formula soot blower of connection and reasonable arrangement quantity in boiler further guarantees to blow grey effect.
In addition, be arranged on the cooling water pipe on the left and right sidewall of described combustion chamber, the lower end is that water inlet, upper end are delivery port, and the place is provided with sewage draining exit in water inlet position.
Beneficial effect: (1) has replaced original steam sootblower with microexplosion formula soot blower, simultaneously the layout of blowing the ash point has also been carried out rational adjustment, flue gas ash and boiler sootblowing steam felt jam exhaust gases passes have effectively been avoided, flue gas is unobstructed, blow ash and good dedusting effect, improve steam production, prolonged maintenance period;
(2) set up cooling water pipe by the left and right sidewall in the combustion chamber, can the flexible modulation fire box temperature by the control cooling water flow, the operation that boiler fully can be safe, reliable, stable;
(3) cancel traveling-grate stoker, only be used for firing biomass fuel, made structure more simple, reduced cost.
