Abstract

An easy-to-retrofit long-life W-flame boiler with micro-oil ignition device arranged on the arch belongs to the technical field of W-flame boilers. To solve the problem of large fuel consumption, fully ignite the pulverized coal when the W flame boiler is ignited with small oil, and avoid damage to the burner. The present invention includes micro-oil ignition pipeline, micro-oil ignition pipeline baffle valve, micro-oil gun, fire detector, thick coal powder pipeline and thick coal powder pipeline baffle valve; A thick separation pipeline, the thick pulverized coal pipeline baffle valve is arranged above the thick coal pulverized pipeline, the micro oil ignition pipeline baffle valve is arranged above the micro oil ignition pipeline, and the micro oil ignition pipeline A micro-oil gun and a fire detector are arranged in sequence, and the micro-oil gun is located below the baffle valve of the micro-oil ignition pipeline, and an oil combustion chamber is formed at the installation position of the micro-oil gun on the micro-oil ignition pipeline.

Description

technical field [0001] The invention belongs to the technical field of W-flame boilers, and relates to a combustion device, in particular to an easy-to-retrofit long-life W-flame boiler with a micro-oil ignition device arranged on the arch. Background technique [0002] The proportion of coal as primary energy production and consumption has remained at around 70%. my country is dominated by thermal power, low volatile matter (dry ash-free base volatile matter Vdaf is less than 20%, including anthracite and lean coal) accounts for more than two-fifths of my country's power coal, this type of coal has a high degree of coalification, and the volatile matter content Low, difficult to ignite; the petrographic structure of coal is tight and stable, the porosity is small, the grindability is weak, the reactivity is low, and the burnout is poor, so it is difficult to ignite and burn out, and requires a higher ignition and burnout temperature. and longer burnout times. There are more...
