Uninterruptible energy-saving technology for coal-fired boilers in power plants

The Targeted In-Furnace Injection Technology (TIFI) developed by U.S. Fuel Technology Co., Ltd. is a combination of chemical agent application and computer simulation control to find the problem in the boiler combustion, using target injection to solve the problem. Problems, engineering techniques to implement energy-saving measures.

The role of chemicals:

1. Adding chemical agent can promote the water gas reaction of unburned carbon in fly ash to generate flammable gas and make carbon particles fully burn to achieve the effect of improving the combustion rate, and reduce the amount and times of the coal ash blowing and improve the energy efficiency.

2. Due to the chemical agent containing MgO, particles with particle sizes of 2 to 4 microns appear in a reasonable position in the jet, the contact surface is extremely large, and the SO3/SO2 produced during the combustion of coal can be neutralized, making the stronger acidic substance become Weakly alkaline or even neutral substances reduce the corrosion of boilers, reduce emissions of SO2, and absorb some of the CO2.

3. After chemical reaction is added, a high-melting Mg mixture will be produced and a layer of cover will be formed at the same time to form a physical barrier on the surface of the sticky material and the heat transfer surface to ensure the stability and reliability of the system operation.

4. Chemicals can decompose water into more efficient combustion components H and OH than O2, promote combustion, and reduce the amount of oxygen used in the combustion environment.

The role of computer simulation:

1. The creation of computational fluid dynamics model can effectively simulate the timely status of the boiler in the combustion process and accurately find the problem

2. It can calculate the heat balance and gas velocity distribution of the unit through calculation, and accurately understand the complex temperature and flow pattern of the boiler.

3, through the simulation can accurately know the demand for chemical agents, the injection of the set-point and number, the target-type injection to the problem in order to achieve the best results

4, on the basis of simulation, combined with on-site debugging can achieve the best results of unimpeded technical engineering implementation

Comprehensive effect:

1. Eliminate the load reduction due to slag removal and soot blowing

2. Save on steam consumption and energy efficiency due to reduced sootblowing

3, due to the improvement of energy efficiency and the full combustion of unburned carbon, saving coal in the case of the same amount of power generation, increase the amount of power generation in the same amount of coal used

4, reduce the amount of oxygen used in the work, save power running costs, improve safety performance

Reducing CO2, SO2 and NOx, reducing the cost of desulfurization; on-line cleaning of boiler coking, reducing coking time for cleaning, increasing power generation capacity and improving production safety, reducing corrosion and greatly reducing pipeline maintenance, improving the stability of system work, and extending the system The service life is widely used in coal-fired power plant boilers, thermal power plants, and factory-owned power plants. The investment return rate is guaranteed to be over 200%. The effect is very significant!
