Embodiment Construction

[0009] In the present embodiment, in the coal-water slurry input device (1), comprise the slurry storage tank (7) of storage fuel and fuel delivery pipeline, on the fuel delivery pipeline, there are low-pressure slurry delivery pump (13), filter (15) and The control valve on the pipeline and the delivery of the coal-water slurry are replaced by the low-pressure slurry delivery pump (13) by the original high-pressure slurry supply pump. This fuel delivery pipe is connected with A pressurized slurry supply tank (58). In the pressurized slurry supply device (II), two pressurized slurry supply tanks (39, 58) of A and B have been adopted, and the two pressurized slurry supply tanks are connected with the compressed air source, and two pressurized slurry storage tanks ( 58, 39) switch between each other through the control of the central control cabinet to deliver high-pressure coal-water slurry to the coal-water slurry spray guns (33, 35) in turn. A booster slurry supply tank fuel...

Abstract

A water-coal slurry boost feeding system consists of a feeding unit, an outputting the slurry to the nozzle, a boosting device between them. The boosting device consists of a boost-feeding tank, a high pressure compressed gas cylinder connected with the boost feeding tank and an air compressor. Furthermore, two or more boost feeding tanks are connected in parallel with their outlets connected with the nozzle in parallel either. A low-pressure slurry-feeding pump can be used to replace the high pressure one and to have multiple boost-feeding tanks in parallel to boost in turn, so that it prevents the high pressure slurry-feeding pump from wear-out easily, lower cost and works normally long and continuously.

Description

technical field [0001] The present invention relates to a pressurized slurry supply system for burning coal-water slurry fuel, more specifically, relates to a pressurized slurry supply system capable of intensified combustion of various coal-water slurry fuels; Coal slurry enhanced combustion system, which can be applied to boilers, kilns and heating devices with various power loads with operating temperatures within 1600 degrees. Background technique [0002] The inventor once filed a patent application (application number 99233530.2) with the title of "high-temperature enhanced combustion device for high-viscosity fuel" to the Chinese Patent Office on June 15, 1999, which disclosed a new high-temperature enhanced combustion of high-viscosity fuel The device, that is, expands and distributes the high-temperature enhanced combustion area into the furnace cavity, etc., so that the thermal efficiency is significantly improved. However, the normal and continuous operation time...
