Advantages of plasma ignition device:
Fuel saving and economy: plasma ignition is a completely different way from oil-gas ignition, which can realize boiler plasma oil-free ignition and stable combustion. The pipe blowing of the new unit will be completed in 168 hours. If this device is used during operation, thousands of tons of fuel can be saved. The ignition cost is only 10~20% of that of traditional oil ignition.
Environmental protection: the thermochemical reaction between pulverized coal and plasma flow and the use of concentrated and dilute combustion can reduce the emission of nitrogen oxides from boilers. Because there is no kerosene mixed combustion, the problem that the electrostatic precipitator cannot be used during boiler start-up and oil injection operation is successfully solved, which is beneficial to environmental protection.
Safety: As long as necessary backup measures are taken, the fuel system of the boiler can be cancelled, thus reducing investment and unsafe factors.
Outstanding characteristics of Wuhan Tianhe technology plasma ignition device in the same industry;
1, high power: the general operating power can be freely adjusted online between 100 and 180 kW, and the maximum power can reach 250KW.
2. Long service life of cathode: the cathode is a hollow cylinder with large ablation area, and is made of ordinary copper. When the working power is 150kw, the service life is longer than170h;
3, reducing power attenuation: air compression is adopted, the cathode and anode are small in size, the whole generator can be directly placed in the burner, and the plasma arc can directly contact with pulverized coal without arc tube guidance;
4. Simple structure: high-frequency non-contact arc ignition is adopted, and the distance between the cathode and the anode remains unchanged during work, so there is no need for a walking motor; The conversion mode of low nitrogen oxides combustion: 1, low excess air combustion: make the combustion process as close as possible to the theoretical air volume. But if the oxygen content (concentration)
2. Complete the fuel combustion process by stages: in the first stage, reduce the gas supply to 70%-75%; In the second stage, the residual air required for complete combustion is injected into the furnace through the special air nozzle OFA arranged above the main burner "upwind of the fire". In order to reduce emissions and ensure the economy and reliability of boiler combustion, it is necessary to correctly organize the air staged combustion process.
Trina Technology's low NOx combustion device has the advantages of reducing NOx emission, improving combustion efficiency, preventing furnace slagging and high temperature corrosion, improving flue gas temperature deviation at furnace outlet, and improving low-load stable combustion (no oil injection) of burner. Plasma treatment of high-risk waste is a new energy-saving and environmental protection technology gradually developed in recent years. Compared with the traditional incinerator, the advantages of plasma technology are as follows:
The treatment temperature can reach more than 1500 degrees, and harmful substances such as dioxins are more thoroughly destroyed;
The gas consumption of plasma treatment is about 10% of incineration, the tail gas is less, the secondary pollutant emission is 2-3 orders of magnitude lower, and the waste residue is harmless without further treatment;
The process control of plasma treatment system is simple, and the type and flow rate of input gas can be adjusted independently, which solves the problem of difficult gas concentration adjustment in traditional incineration method.
The plasma device has the advantages of small volume, simple auxiliary equipment and low maintenance cost. The total equipment area is about 1/4 of the incineration plant.
Hazardous wastes can be turned into raw materials for the production of synthetic gas, which is in line with the concepts of new energy, environmental protection, zero carbon emission and sustainable development, with good economic benefits and short payback period.
