Abstract
The utility model provides a fire living beings traveling grate boiler, including furnace, boiler face arch, feeding barrel and traveling grate stoker, feeding barrel's export and the top that the boiler face arch all is located the traveling grate stoker anterior segment, the bottom of boiler face arch highly is not higher than the height of feeding barrel export, forms a long and narrow buffering area between the bottom of boiler face arch and the traveling grate stoker, should buffering takes and to keep apart furnace's high temperature. Owing to cushion the existence in area, biomass fuel falls from the feeding barrel export and can not burn after traveling grate stoker goes up at once, but follows the grate and to the motion of furnace direction, just ignited after leaving one section regional distance of blanking, because the buffering takes the oxygen content less, biomass fuel only just can begin violent burning behind entering furnace. Like this, the regional temperature of blanking just can obtain control, can not rise de taigao, and the circumstances that can effectively avoid feeding barrel to be burnt out takes place, and owing to the existence in buffering area, furnace flame hardly fires and gets into in the feeding barrel simultaneously.
Description
Technical field
The utility model relates to a kind of biomass-burning chain grate boiler.
Background technology
For existing biomass-burning chain grate boiler, due to blanking barrel outlet next-door neighbour burner hearth, biomass fuel is fallen on traveling-grate stoker can be ignited very soon by blanking barrel outlet, the temperature at such blanking port place will be very high, long-term high temperature not only can make the variable color of boiler foundation front panel, but also blanking barrel can be crumpled, thus causes damage to boiler front arch, face arch avalanche may be caused, flame even also can occur and fire situation into blanking barrel.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of biomass-burning chain grate boiler that blanking barrel can be avoided to be burned.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of biomass-burning chain grate boiler, comprise burner hearth, boiler front arch, blanking barrel and traveling-grate stoker, the outlet of described blanking barrel and boiler front arch are all positioned at the top of traveling-grate stoker leading portion, the bottom level of described boiler front arch is not higher than the height of blanking barrel outlet, form a long and narrow buffer strip between the bottom of boiler front arch and traveling-grate stoker, this buffer strip can be isolated the high temperature of burner hearth.
Adopt technique scheme, due to the existence of buffer strip, biomass fuel is fallen after traveling-grate stoker can't burn at once from blanking barrel outlet, but move to burner hearth direction with fire grate, just ignited after leaving blanking region one segment distance, because buffer strip oxygen content is less, biomass fuel only just can start vigorous combustion after entering burner hearth.Like this, the temperature in blanking region just can be controlled, and can not be too high, and the situation that can effectively avoid blanking barrel to be burned occurs, and simultaneously due to the existence of buffer strip, furnace flame is difficult to combustion and enters in blanking barrel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of biomass-burning chain grate boiler as shown in Figure 1, comprise burner hearth 3, boiler front arch 2, blanking barrel 1 and traveling-grate stoker 4, the outlet of described blanking barrel 1 and boiler front arch 2 are all positioned at the top of traveling-grate stoker 4 leading portion, the bottom level of described boiler front arch 2 is not higher than the height that blanking barrel 1 exports, form a long and narrow buffer strip 5 between the bottom of boiler front arch 2 and traveling-grate stoker 4, this buffer strip 5 can be isolated the high temperature of burner hearth 3.
Operation principle of the present utility model is: due to the existence of buffer strip 5, biomass fuel is fallen after traveling-grate stoker 4 can't burn at once from blanking barrel 1 outlet, but move to burner hearth 3 direction with fire grate, just ignited after leaving blanking region one segment distance, because buffer strip 5 oxygen content is less, biomass fuel only just can start vigorous combustion after entering burner hearth 3.Like this, the temperature in blanking region just can be controlled, and can not be too high, and the situation can effectively avoiding blanking barrel 1 to be burned occurs, and simultaneously due to the existence of buffer strip 5, furnace flame is difficult to combustion and enters in blanking barrel 1.
Claims (1)
1. a biomass-burning chain grate boiler, comprise burner hearth, boiler front arch, blanking barrel and traveling-grate stoker, it is characterized in that: the outlet of described blanking barrel and boiler front arch are all positioned at the top of traveling-grate stoker leading portion, the bottom level of described boiler front arch is not higher than the height of blanking barrel outlet, form a long and narrow buffer strip between the bottom of boiler front arch and traveling-grate stoker, this buffer strip can be isolated the high temperature of burner hearth.
