At the same time, the features of pipe blowing technology for the .

The pipe blowing process of one supercritical once-throng boiler in Guangdong province is introduced and analyzed.

The article highlighted furnace cold dynamical test, the steady pressure pipe blowing, .

Introducing a kind of boiler blowpipe about boiler supperheatera ndb oilerr eheaterb etweent heirc onjunction piping to clean all kinds of miscellaneous objects that stay in the system, avoiding them affecting turbine and boiler equipments, insure the steam good quality.

of Ignition and Blowpipe for NaYong Power Plant Unit #1, and summed up the equipment problem and defect of discovery in the ignition blowpipe course as well as experience lesson that the ignition blowpipe should be absorbed in the course .

If we add a blowpipe to the rear of the trough, and change the screen to a cover plate which can be lifted, the mesh would be cleaned thoroughly, and the tobacco smalls adhered to the trough can be wiped off.

On the basis of the characteristics of BF Pulverized coal combustion, the combustion of pulverized coal in the blowpipe and tuyere is simulated step by step.

In the process of pulverized coal injection (PCI) into blast furnace, the blowpipe plays an important role in pre mixing the pulverized coal and oxygen, pre heating them and improving the pulverized coal pyrolization and combustion of the coal.

Based on the study of gas solid flow field in blowpipe of BF with oygen enriched PCI, the oxygen and coal concentration distribution inside the blowpipe were simulated and discussed, including the influence of position and inserting angle of the oxygen coal lance, the pattern of the oxygen enriched jet, as well as grain size of the coal.

Intermittent pressure steam purging for 1 000 MW ultra-supercritical units;
