Abstract
The utility model discloses a high-low pressure energy-saving biomass combustion apparatus. A chain grate stoker is disposed below a furnace body. A front arch and a rear arch are respectively disposed in the front and rear parts of a hearth of the furnace body. The front segment of the hearth is a low-pressure auxiliary burning segment, and the middle and rear segment of the hearth is a high-pressure main burning segment. The chain grate stoker is provided with an auxiliary primary air port below and at the tail end of the low-pressure auxiliary burning segment. The chain grate stoker is provided with an eddy current reinforcing primary air port below the high-pressure main burning segment. The high-low pressure energy-saving biomass combustion apparatus is advantageous in that the biomass combustion apparatus is suitable for a plurality of biomass fuels; combustion efficiency is high, resources and energy can be saved and consumption can be reduced.
Description
Technical field
The utility model relates to a kind of burner, relates in particular to a kind of high-low pressure energy saving biomass combustion apparatus.
Background technology
The traditional fuel such as oil, colliery belongs to non-renewable resources, along with exploitation for a long time, and present growing tension, price goes up year by year, and China is large agricultural country, has abundant biomass energy, biomass energy is developed and utilized, certainly will can slow down present energy-intensive situation.At present owing to lacking combustion apparatus special-purpose, specialty, be generally that operation is complexity comparatively with living beings utilizations that then act as a fuel of vaporizing, liquefy, operation cost is higher.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of efficiency of combustion high, is applicable to the high-low pressure energy saving biomass combustion apparatus of various biomass fuels.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of high-low pressure energy saving biomass combustion apparatus, it is characterized in that: traveling-grate stoker is installed below body of heater, be provided with face arch, rear arch before and after in the burner hearth of body of heater, in burner hearth, leading portion is low pressure auxiliary combustion section, and the posterior segment is high pressure master burning zone; Traveling-grate stoker is provided with auxiliary primary air nozzle at low pressure auxiliary combustion section lower position and tail end, and traveling-grate stoker is provided with eddy current at high pressure master burning zone lower position and strengthens primary air nozzle.
The air inlet bore of described auxiliary primary air nozzle is less than the air outlet bore.
Described eddy current is strengthened the air inlet bore of primary air nozzle greater than the air outlet bore, is provided with spiral ridge in the air channel, and the air outlet place is provided with control valve.
The utlity model has following beneficial effect: at first fuel enter low pressure auxiliary combustion section, carry out pre-burning under an auxiliary wind that comparatively relaxes is auxiliary, then enter high pressure master burning zone, the eddy current large at wind speed, that blast is strong is strengthened burning rapidly under a wind effect, in the auxiliary wind effect of burner hearth tail end warp, unburnt part is fully burnt at last.It is applicable to multiple biomass fuel, and can realize that efficiency of combustion is high, saving resource, energy-saving and cost-reducing effect.
Description of drawings
Fig. 1 is the utility model structural representation.
In figure, 1, low pressure auxiliary combustion section, 2, body of heater, 3, high pressure master burning zone, 4, rear arch, 5, traveling-grate stoker, 6, spiral ridge, 7, eddy current strengthens primary air nozzle, 8, auxiliary primary air nozzle, 9, face arch.
The specific embodiment
Referring to shown in Figure 1, body of heater 2 belows are equipped with traveling-grate stoker 5, are provided with face arch 9, rear arch 4 before and after in the burner hearth of body of heater 2, and in burner hearth, leading portion is low pressure auxiliary combustion section 1, and the posterior segment is high pressure master burning zone 3; Traveling-grate stoker 5 is provided with auxiliary primary air nozzle 8 at low pressure auxiliary combustion section 1 lower position and tail end, the air inlet bore of auxiliary primary air nozzle 8 is less than the air outlet bore, therefore wind speed comparatively relaxes, play respectively with fuel pre-burning with the effect of the sufficient fuel after-flame of unburned; Traveling-grate stoker 5 is provided with eddy current at high pressure master burning zone 3 lower positions and strengthens primary air nozzle 7, its air inlet bore is greater than the air outlet bore, be provided with spiral ridge in the air channel, exportable wind speed is high, the eddy current wind that blast is strong impels fuel conflagration, and the air outlet place that eddy current is strengthened primary air nozzle 7 is provided with control valve, but based on fuel is regulated, and guarantees that fuel combustion is abundant.
