On April 24th, with the 750-ton crane arriving and completing its testing, the ultra-low emission renovation project for the thermal power boilers at Jinling Petrochemical officially commenced. It has been learned that after the renovation is completed, the concentrations of NOx, SO2, and dust in the boiler exhaust gases will meet the ultra-low emission standards of 50 milligrams per cubic meter for NOx, 35 milligrams per cubic meter for SO2, and 5 milligrams per cubic meter for dust. This year is a crucial one for the company to accelerate industrial upgrading and improve efficiency. For thermoelectric boilers, they will face even greater pressures regarding supply assurance and environmental protection. As required by the environmental protection authorities in Nanjing, the ultra-low emission upgrades for two CFB boilers and one coal powder boiler were to be completed by 2017, with all boilers to have undergone such upgrades by 2018. To this end, the company attached great importance to the matter and promptly initiated reforms of Boiler No. 3 and the desulfurization tower. Measures such as the use of tube-type dust and mist removers, the replacement of high-efficiency catalysts, the optimization and modification of the ammonia injection grids and related systems, as well as the addition of spray layers in the desulfurization tower, were taken to ensure that the flue gas emissions meet ultra-low emission standards after the reforms.
It was shut down directly when the funding ran out
All need to be modified; environmental protection is very important.
The goal is to contribute to emission reduction
These are the strict targets set for various regions this year; time is running out
I am very interested in this, and I have the following questions that require further discussion: 1. What are the flow rate, temperature, pressure, sulfur oxide levels, nitrogen oxide levels, and dust levels of the boiler exhaust gas before it enters the desulfurization and denitration system? 2. What are the water and electricity consumption metrics, as well as the operation and maintenance costs? What is the budget for spare parts for annual operation and maintenance? 3. What is the approximate budget required to build a flue gas desulfurization and denitrification facility with a capacity of 200,000 cubic meters per hour? Thank you!
