TH48015B - A concentrator for pulverized coal and a boiler using combustion pulverized coal. - Google Patents

Abstract

DC60 (07/07/57) This invention provides an improvement in the vertical direction concentration distribution at the channel. Import of crushed coal spreader The pulverized coal was distributed evenly to each crushed coal burner, the pulverized coal spreader (17a to 17d) and the gas particle flow modulation device (20) in place. On the top of the pulverized coal spreader (17a to 17d) and below in the pulverized coal pipeline (13a to 13d), the concentrations of crushed coal are delivered to the separation tubes (18a, 18b). , Gas particle flow modulation device (20), consisting of sheet-shaped components, positioned according to The significant total width of the pulverized coal pipeline (13a to 13d) has a square shape. Significance when viewed in the diagram The front edge of the gas particle flow modulator is installed. It rotates around its axis with the lower surface of the crushed coal pipeline (13a to 13d) and the angles are formed. Between the top surface of the gas particle flow modulator and the bottom surface of the pulverized coal pipeline (13a to 13d) that can be adjusted automatically based on the signal coming from the attached flow sensor. Located with each separate pipe (18a, 18b), this invention provided improvements to the vertical concentration distribution at the inlet channels. Of pulverized coal spreader And distribute the crushed coal evenly to each crushed coal burner Crushed coal disperser (17a to 17d) and gas particle flow adjustment device (20) placed on The upward side of the crushed coal spreader (17a to 17d) and the bottom in the pulverized coal pipeline (13a to 13d) serves to adjust the concentration of crushed coal delivered to the separation pipe (18a to 18b. ) And gas particle flow modulation device (20), which is composed of a plate-shaped element, according to the The total width of the pulverized coal pipeline (13a to 13d) has a rectangular shape when viewed in the diagram, with the front edge of the gas particle flow modulator mounted as a rocker on the lower surface. Of the crushed coal pipeline (13a to 13d) and there is an angle formed between the top surface of the flow regulator Of gas particles and the bottom surface of the pulverized coal pipeline (13a to 13d) with automatic adjustable According to the signal coming from the flow sensor mounted to each separate pipe (18a, 18b)
