pulverized coal boiler stability

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
Automatic production line.

The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.

Laboratory Studies of Lifted Pulverized Coal Flam

and the range of pulverized coal burner’s stability, which produces serious problems for boiler designers and power plants. It motivates the development of new engineering tools for the


the efficiency of existing coal fired plants. Operation of non-optimized boiler can lead to reduced boiler efficiency, increased excess air requirements, delayed combustion, increased heat loss, high CO and NOx emissions and many other. Optimization of combustion in pulverized coal fired boiler is very important today for every thermal power plant.

Pulverized coal-fired boiler - Wikiped

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.

Pulverized coal combustion boiler efficient control -

Eco–control of pulverized coal combustion process Opportunity to assess the quality of combustion is critical to proper operation of the boiler's energy [2]. In the case of combustion flow in layers, it translates to the speed of chemical reactions, heat transfer efficiency, flame stability and the generation of NOx and CO. Literature [1-3]

Mechanism analysis on the pulverized coal combustion flam

The gas-solid two-phase flow, pulverized coal combustion and NOx emission characteristics of a single low NOx swirl burner in an existing coal-fired boiler was numerically simulated to analyze the mechanisms of flame stability and in-flame NOx reduction.

Establishment of combustion stability index of pulverized-co

The problem on combustion stability of pulverized-coal is one of the most important factors to the security and economy of the boiler's operation in a power plant.
