SCR treatment does not need to modify the boiler body, but only directly deals with the boiler tail gas, which has no impact on the boiler body. At the same time, a real-time online monitoring and control system is implemented to monitor the NOx concentration and O2 content before and after the tail gas in real time, and the treatment efficiency reaches more than 95%.

1、 What is natural gas annealing furnace?

The natural gas annealing furnace is an energy-saving and environment-friendly heat treatment device with high safety, good energy-saving effect and good temperature uniformity. It is mainly applicable to mining machinery, steel structure welding and other mechanical products. It can replace the refractory brick electric furnace with suitable heat treatment on the market.

2、 Does the natural gas annealing furnace produce waste gas after burning?

After the natural gas annealing furnace is completely burned, the main flue gas produced contains water, nitrogen oxides and carbon dioxide. If it is not fully burned, carbon monoxide will also be produced, causing poisoning.

When nitrogen dioxide exceeds 0.04% of the air content, it will cause people to have difficulty breathing or suffocation. Keep good ventilation during reuse. However, there will also be incomplete combustion of natural gas in the annealing furnace, which will lead to the imagination of black smoke, resulting in the emission of waste gas particles, air pollution and climate warming.

The emission of nitrogen oxides (NOx) will endanger human body and mind, stimulate people's eyes, nose, throat and lung respiration, easily cause bronchitis and pneumonia, and also induce lung cell canceration; It will also destroy the ecology and leaf tissue, inhibit their growth, and form urban smog, affecting visibility; It also produces acid rain.
