What is the judgment standard of boiler anoxic combustion?

24 Jun 2022

Boiler is a kind of important thermal power equipment, which is widely used in factory power, building heating, people's life and other aspects, and is in great demand. The principle of industry is to release heat energy by burning fuel, and the boiler's anoxic combustion is not conducive to the release of heat energy. What is the judgment standard of boiler anoxic combustion?

 

What is anoxic combustion?

The combustion reaction can be said to be the oxidation-reduction reaction between the combustion substance and oxygen. When the amount of oxygen is insufficient, the reaction is the anoxic reaction. At this time, incomplete combustion will produce incomplete combustion oxides such as carbon monoxide. The calorific value of oxygen-deficient combustion is not high, and the oxides that produce incomplete combustion are mostly toxic compounds. Oxygen-enriched combustion has a high calorific value, and most of the generated oxides exist in the air with little or no pollution.

 

When the boiler is in anoxic combustion, the combustion is unstable and it is easy to turn off, the carbon content of fly ash will increase, and the boiler is prone to coking due to anoxic combustion. Overoxygen is easy to burn with rich oxygen, and the fan economy is poor, which increases the conversion rate of NOX. What is the judgment standard of boiler anoxic combustion?

 

Judgment of boiler anoxic combustion

  1. In the process of daily operation, the user can judge the boiler's anoxic combustion by detecting the CO content in the flue gas. If the CO content is high, it means that the fuel is not burnt out, and the boiler is in anoxic combustion; Less CO means the fuel is burnt out.
  2. The excess air coefficient is too small, which will cause incomplete fuel combustion, reduce the thermal efficiency of the boiler, and pollute the heating surface and environment. If the excess air coefficient is too large, the power consumption of induced draft fan will increase, the heat loss of boiler smoke exhaust will increase, and the thermal efficiency of boiler will also decrease. When the sum of various heat losses of the boiler is the smallest, that is, the excess air coefficient when the boiler efficiency is the highest is called the optimal excess air coefficient.

 

The above is the introduction of the judgment standard of boiler anoxic combustion, and I hope it will be helpful to everyone. Regarding the judgment of boiler's anoxic combustion, ZOZEN Boiler will provide professional technical guidance, determine the judgment standard of boiler's anoxic combustion according to the actual operation situation, and help users realize economic operation.
