Description
Technical Field
The utility model relates to a special oxygen boosting air separation plant of coal slurry stove.
Background
The water-coal-slurry boiler refers to a boiler using water-coal-slurry as fuel. The coal water slurry is a liquid prepared by mixing about 70% of coal powder, about 30% of water and a small amount of medicament, can be pumped, atomized, stored and transported like oil, and can be directly used for burning of various boilers and kilns. The traditional combustion mode of coal is changed, and the great environment-friendly and energy-saving advantages are displayed. Especially in recent years, after a technical route of waste recycling is adopted, the environment-friendly coal water slurry which is successfully developed can greatly improve the environment-friendly benefit of the coal water slurry on the premise of not increasing the cost. Under the guarantee of rich coal data in China, the coal water slurry also becomes one of the most basic and most economic clean energy sources for replacing oil, gas and other energy sources.
The suspension atomization coal water slurry boiler mainly adopts an atomization combustion mode, generates less evaporation (generally less than 10 t/h), and is more suitable for printing and dyeing enterprises. The suspension atomized water-coal slurry boiler integrates the advantages of fuel oil and coal, and is conveyed in liquid state and atomized and combusted. The combustion efficiency can reach 98-99%, and the thermal efficiency can reach more than 82%. Has the obvious characteristics of low operation cost, energy conservation and environmental protection.
Under the condition, the coal water slurry airflow is radiated by the walls of the hearth and high-temperature flame to quickly heat coal particles suspended in the airflow until enough heat is obtained and a certain temperature is reached, and then the ignition combustion is started. The operation load of the boiler depends on the property of fuel and the operation condition, namely when the boiler load is low, the average smoke temperature of a hearth is reduced, and the smoke temperature of a combustor area is reduced along with the reduction of the average smoke temperature. The lowest operation load of the atomized combustion type water-coal slurry boiler is about 50 percent.
After the oxygen-enriched air separation equipment is combined with the air compressor, the combustion intensity and the combustion efficiency can be improved, and the combustion speed is accelerated. However, when the adsorption tower begins to generate gas, unqualified gas is generated and generally discharged as waste gas, which is not fully utilized, and energy is wasted.
