Technology Introduction

Biomass biogas is a clean and environment-friendly renewable energy. Using biomass biogas for power generation and making full use of waste heat resources in the process of power generation is an important way to develop green circular economy and realize sustainable development. Biomass biogas enters the generator set, and the internal combustion engine converts the chemical energy of biomass biogas into mechanical energy, and then converts the mechanical energy into electrical energy. In this process, a large amount of waste gas nitrogen oxides will be generated. In order to meet the environmental protection regulations, a set of device capable of treating nitrogen oxides needs to be installed.

Technical advantages

1. Mature and reliable technology, high denitration efficiency and reducing ammonia escape

2. Fast reaction speed

3. Uniform ammonia injection, low resistance, low ammonia consumption and relatively low operation cost

4. It can be applied to denitration at low, medium and high temperatures

Denitration treatment of power plant

Selective catalytic reduction (SCR) is used to control NOx in diesel engine exhaust. NH3 or urea (usually urea aqueous solution with mass ratio of 32.5%) is used as reducing substance. Under the condition that O2 concentration is more than two orders of magnitude higher than NOx concentration, under the action of certain temperature and catalyst, NH3 is used to reduce NOx to N2 and H2O. Because NH3 is highly selective, NOx is preferentially reduced, It does not react with O2 first, so it is called "selective catalytic reduction". For excess NH3, a certain proportion of ammonia escape catalyst (ASC) is coated at the end of SCR carrier to ensure that NH3 reacts with O2 to generate N2 and H2O and avoid secondary pollution caused by NH3 leakage. The exhaust temperature after diesel engine or gas engine turbine is generally in the range of 300 ℃ to 500 ℃, which meets the temperature conditions required for medium temperature catalytic reaction. If the temperature after vortex is higher than 500 ℃, high-temperature catalyst shall be considered, and the system cost will increase in a certain proportion.
