High-pressure ammonia water smokeless coal charging
Thread Content
Everyone discussed the optimization of smokeless coal loading operations, as well as their advantages and disadvantages
It probably refers to smoke-free coal loading using steam or high-pressure ammonia under negative pressure, right? Maintaining its good performance depends on the operating condition of the associated equipment, such as high-pressure ammonia water pumps and three-way ball valves ； Furthermore, there is a more appropriate operational pressure that has been proven effective through practice ； It is best to be equipped with an automatic control system to stabilize operations and save energy. Its greatest advantage is that it requires less investment and is simpler to operate compared to other smoke removal methods. However, its effectiveness can be variable and not stable; moreover, it easily allows the absorption of impurities such as free carbon, which affects the quality of tar. The air drawn in increases the oxygen and nitrogen content in the gas, which may have a negative impact on the safe operation of electric tar collectors and fans, as well as on the use of the gas.
Coal charging with high-pressure ammonia without generating smoke leads to an increase in the dust content and free carbon in the tar, and may even cause emulsification of the tar, making it difficult to separate the tar from the ammonia. This affects the quality of chemical products as well as the further processing of the tar. This is a shortcoming of smoke and dust removal in top-mounted coke ovens.
