The invention discloses an environmental-protection coal saving agent and relates to a coal saving agent, which solves the defects that the existing coal saving agent has large additive amount, pollutes the environment and does not meet the Greenman blackness. By weight percentage, the environmental-protection coal saving agent comprises 5 to 10 percent of activator, 30 to 40 percent of modifier,5 to 10 percent of smoke suppressor, 5 to 10 percent of purificant, 2 to 8 percent of oxidant, 30 to 35 percent of swelling agent and 5 to 10 percent of sulfur fixing agent. The environmental-protection coal saving agent has the advantages of small additive amount, environmental protection, wide application scope and simple use. The additive amount of the coal saving agent is only 3 permillage ofthe weight of coal, but the energy-saving rate reaches more than 10.81 percent; and the harmful gas is reduced more than 70 percent and the Greenman blackness is less than 1 class.

The invention provides a process nozzle and a system for gasifying water coal slurry. The process nozzle comprises a first oxygen channel, a water coal slurry channel, a second oxygen channel, a first cooling water jacket and a cooling water coil, wherein the first oxygen channel comprises a first oxygen channel inlet and a first oxygen channel outlet; the water coal slurry channel comprises at least one water coal slurry channel inlet and a water coal slurry channel outlet; the second oxygen channel comprises a second oxygen channel inlet and a second oxygen channel outlet; the first cooling water jacket comprises a first cooling water jacket inlet and a first cooling water jacket outlet; and the cooling water coil comprises a cooling water coil inlet and a cooling water coil outlet. The process nozzle is characterized in that: the first oxygen channel is positioned at the central position of the process nozzle; the water coal slurry channel is positioned between the first oxygen channel and the second oxygen channel and surrounds the periphery of the first oxygen channel; and the second oxygen channel surrounds the periphery of the water coal slurry channel. The process nozzle reduces the length of combustion flame more effectively, reduces the ablation of flame on a refractory brick, promotes the mixing and atomization of water coal slurry and oxygen and improves gasification efficiency.

The invention discloses a stove fire cover. The side wall of the stove fire cover is provided with an outward extending waterproof brim. The stove fire cover is provided with main fire holes and flamestabilizing holes. The main fire holes are distributed in the side wall and located below the waterproof brim. The flame stabilizing holes are formed in the lower surface of the waterproof brim towards the main fire holes. According to the stove fire cover, the flame stabilizing holes for stabilizing flames of the main fire holes are formed in the specific positions of the lower surface of the waterproof brim so that the length of the flames of the main fire holes located in the lower end of the waterproof brim can be increased, the flames can further outwards extend, and accordingly, under the situation that the extending length of the waterproof brim is large, the flames can be prevented from being hindered by the waterproof brim, so that the heating efficiency of the stove fire cover is improved, and meanwhile the off-flame situation can be avoided.

The invention provides a hierarchical adding device for total-oxygen combustion fuel of glass melting furnaces. The device mainly comprises a main fuel pipe (2), a combustion-supporting oxygen pipe (7), a main burner (11), minor fuel pipes (12), as well as valves which are connected with the bodies of the combustion-supporting oxygen pipe (7), the main fuel pipe and the minor fuel pipes and play a certain role in controlling and regulating, wherein the main burner (11) has a casing-type structure and is sleeved with the body of the right part of the main fuel pipe (2); two minor fuel pipes (12) are provided, are symmetrically distributed on two sides of the main burner (11), and are parallel to the main burner; and the right end of the body of the combustion-supporting oxygen pipe (7) is connected and communicated with the main burner through a bent pipe. The device regulates the length, coverage area, temperature and other parameters of flame by adjusting the amount of fuel used between the main burner and the two minor fuel pipes so as to ensure the complete combustion of the fuel, has the advantages of saving energy, reducing emission, benefiting environmental protection and the like, and is especially applicable to total-oxygen combustion glass melting furnaces which takes natural gas as fuel.

The invention relates to an oxygen-rich inclined-flame combustion method of a flat glass melting furnace and a combustion device. The combustion device comprises a feeder nose, a melting part, a neck and a cooling part. A breast wall is arranged outside the melting part. The breast wall, close to left and right sides of the feeder nose, is provided with smoke vents. Several oxygen-rich inclined-flame combustors are arranged at intervals at left and right sides of the breast wall. The included angle between flame of the oxygen-rich inclined-flame combustors and the breast wall is 30-150 degrees. Each oxygen-rich inclined-flame combustor contains a spray gun and a burner block, wherein the spray gun comprises an oxygen spray gun and a fuel spray gun. The oxygen-rich inclined-flame combustor also comprises a control part which adopts subsection control. According to a temperature curve of a glass melting furnace, distribution ratio of each section of combustor for conveying fuel is set. By an oxygen-rich inclined-flame combustion mode, temperature field and airflow field inside the glass melting furnace are optimized, heat exchange efficiency can be enhanced, erosion of exhaust gas to furnace crown is minimized, and service life of the glass melting furnace is prolonged.

The invention relates to a bauxite shaft kiln combustion device which comprises a fuel channel, a hot air channel and a combustion plate. One end of the fuel channel is sealed through a cover plate, a maintenance hole is formed in the cover plate, the other end of the fuel channel is communicated with the hot air channel through a flange, a fuel inlet is formed in the fuel channel, the hot air channel is a double-layer casing pipe, the double-layer casing pipe comprises an inner pipe and an outer pipe, the annular space between the inlet end of the inner pipe and the inlet end of the outer pipe is sealed through a steel board, the inner pipe and the outlet end of the outer pipe are fixed together through the combustion plate, a hot air inlet is formed in the outer pipe, and a plurality of baffle boards which are obliquely arranged along the outer surface of the inner layer of the casing pipe are arranged on the outer surface of the inlet end of the inner pipe. The bauxite shaft kiln combustion device can improve combustion efficiency, energy is saved by more than 30%, consumption is reduced by more than 30%, carbon emissions are reduced, and environmental pollution is reduced.

The invention provides an electricity thick liquid torch trigger device, has a cabin including a pole piece frame, this cabin interplantation goes into one and extremely excellent and form one aroundthe gas collecting groove in between the extremely excellent and cabin wall, a pole piece has been put admittedly to the bottom of this pole piece frame, this pole piece has a core hole, inner this gas collecting groove of intercommunication in this core hole, the bocca of torch is starched to the outer end in this core hole as the electricity, wherein should extremely excellently have an electricion throws the end, this electric ion throws the end and is close to in the inner in this core hole, it is a conical hole wall to form between the inner in this core hole and the outer end, thisconical hole wall is expanded gradually to this outer end and is formed by this the inner, so, improve tradition electricity thick liquid torch because of the narrow and shallow limited problem of flame temperature and flame length that causes in core hole.
