Summary of the invention
The purpose of this invention is to provide a kind of parallel-connection type coal-burning device, the quantity of heat given up adjustable range of this coal-burning device is big, and energy savings does not need repeatedly to light a fire.
The object of the present invention is achieved like this: the present invention includes two in parallel coal-burning devices, each coal-burning device comprises shell, refractory masses, internal communication mouth, once advances coal air inlet, secondary air mouth, air outlet, slag notch and support.
Have the internal communication mouth in the middle of two coal-burning devices.The coal-burning device shell is the drum of both ends open, is equipped with on the end opening therein and once advances the coal air inlet, is equipped with air outlet on other end opening, in the coal-burning device enclosure refractory masses is housed.At each coal-burning device circumference shell upper edge circumference several secondary air mouths are installed, the secondary air mouth is along outer cover length direction distribution plurality of rows, the secondary air mouth is a tubulose, tangentially pass refractory masses along circumference, communicate the tangential approach axis mirror image symmetry of the secondary air mouth of two coal-burning devices with the coal-burning device inner chamber.Each coal-burning device bottom has slag notch.Burner housing is installed on the support.
The course of work of the present invention realizes like this: at first a coal-burning device inside is heated, its internal temperature is reached more than the coal dust burning-point, once advance the coal air inlet by this coal-burning device then and be blown into wind one time, and be blown into coal dust simultaneously, be blown into secondary wind by this coal-burning device secondary air mouth again, coal dust is taken fire in this coal-burning device, the high-temperature gas after the burning flows out from this coal-burning device air outlet, enter the firing equipment of the needs connection of back, finish heating.High-temperature gas enters another coal-burning device in parallel by the internal communication mouth simultaneously, to this coal-burning device heating, this coal-burning device once advances the coal air inlet and is blown into wind one time then, and be blown into coal dust simultaneously, be blown into secondary wind by this coal-burning device secondary air mouth again, coal dust is taken fire in this coal-burning device, and high-temperature gas enters the back firing equipment.Liquid slag flows out from slag notch.When the firing equipment that connects later when coal-burning device required output low in calories, that closes one of them coal-burning device advanced coal and secondary air, only works with another coal-burning device, realizes output low in calories.
Because two coal-burning device parallel connections can be worked simultaneously, also can only work independently, thereby the quantity of heat given up adjustable range is big with a coal-burning device.When output low in calories, only under minimum output state, work with a coal-burning device, can energy savings.When the needs high heat was exported, another coal-burning device can be lighted at any time, did not need the advantage of repeatedly lighting a fire so have.
