Abstract
The utility model relates to a coal chain boiler anti-coking device, which comprises pulverized coal devices, wherein the pulverized coal devices comprise fixing rods and round teeth, and the round teeth are uniformly distributed on the bottom portions of the fixing rods. The pulverized coal devices are uniformly arranged on the upper portions of boil grates according to the thickness of upper coal layers of boiler coal rows, and the round teeth between the pulverized coal devices are arranged in a cross mode. The coal chain boiler anti-coking device has the advantages of simple structure, low investment in technological upgrading and obvious energy-saving benefit, and is widely applied.
Description
Technical field
The utility model belongs to burning coal stove technical field, is specifically related to a kind of combustion coal chain boiler anti-coking device.
Background technology
At present, phenomenon of coking appears in the coal seam of the chained coal fired boiler on the market easily in combustion process, has increased the labour intensity in workman pine coal seam, and the boiler oil coal combustion insufficient waste that causes fuel that causes because of the coal seam coking.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of simple in structure, and investment in technological upgrading is little, pre-anti-coking, and caking can fully burn the coal seam, widely used a kind of combustion coal chain boiler anti-coking device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of combustion coal chain boiler anti-coking device comprises the fine coal device, and the fine coal device is made of fixed bar, knuckle-tooth, and knuckle-tooth is uniformly distributed in bottom of fixed.
Preferably, described fixed bar, knuckle-tooth all adopt resistant to elevated temperatures metal material processing, the shape indention.
Preferably, the distance between the described knuckle-tooth is 30-50cm.
Preferably, the fine coal device that described fixed bar, knuckle-tooth constitute is according to the thickness in coal seam, steam coal row top, evenly distribute be installed in the boiler grate top 20-30cm place, the knuckle-tooth between each fine coal device is the staggered form installation.
Advantage of the present utility model: simple in structure, investment in technological upgrading is little, pre-anti-coking, and caking can make that the coal bed on the fire grate can be loose uniformly in the coal stove, can fully be burnt in the coal seam, can be effectively energy-conservation, be widely used.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model scheme of installation.
1, fixed bar 2, knuckle-tooth 3, fine coal device 4, coal seam, fire grate top
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, a kind of combustion coal chain boiler anti-coking device comprises fine coal device 3, and fine coal device 3 is made of fixed bar 1, knuckle-tooth 2, and knuckle-tooth 2 is uniformly distributed in fixed bar 1 bottom.
Described fixed bar 1, knuckle-tooth 2 all adopt resistant to elevated temperatures metal material processing, the shape indention.
Distance between the described knuckle-tooth 2 is 30-50cm.
The using method of this device is as follows:
Referring to Fig. 2, the fine coal device 3 that fixed bar 1, knuckle-tooth 2 constitutes is according to the thickness in coal seam, steam coal row top, evenly distribute be installed in the boiler grate top 20-30cm place, the knuckle-tooth 2 between each fine coal device 3 is the staggered form installation.
The knuckle-tooth quantity of the every fixed bar 1 in the present embodiment and the coal that is arranged in the bunker coal that the distance between the fine coal device of fire grate top uses according to the tonnage size and the boiler of boiler are decided.Fixed bar is fixed on the both sides of boiler setting, and is fixing firm firm, and the resistance that prevents the grate furnace motion is excessive and cause the fine coal device and depart from the fixed position, causes boiler damage and blowing out.This utility model has simple in structure, and investment in technological upgrading is little, and energy-saving benefit is obvious, is widely used.
