Embodiment Construction

[0044] figure 1 A vent regulator assembly constructed in accordance with a preferred aspect of the invention is shown. The draft regulator assembly 10 is shown aligned with the furnace wall burner ports, attached to the boiler wall 14, and installed inside the "wind box" 12. Fuel pipes 20 protrude from the outside of the outer windbox furnace wall 22 . In this configuration, fuel tube assembly 20 includes outer fuel tube 22a surrounding inner air or fuel tube 70 and aligning them axially. The outer fuel pipe 22a delivers air and fuel to the combustion zone designated by reference numeral 26 . Fuel, which may include pulverized coal, is received through inlet 24 between fuel line 70 and outer fuel line 22a. In such an arrangement, an oil burner (not shown) may be mounted on the inner tube 70 . Burner assemblies can fire coal or oil or a combination, depending primarily on the application and / or boiler conditions. The fuel line assembly is a conventional assembly and is not...

Abstract

This invention relates to double ventilate adjustor and burst spray mouth in the low nitrogen oxidation burst device system, wherein, The said ventilate adjustor comprises one pair of supportive board suspension rack to guide burst air into shell entrance composed of one block gate with one pair of parallel edges, rivet structure and block gate rotation axis; The said spray mouth comprises ring channel to exit connected to the powder mineral burst area and the ring channel is between the inside column part and shell parts; the burst flow area device comprise one shade part, one secondary parts at certain angle to the first one.

Description

technical field [0001] The invention relates to a low nitrogen oxide burner system suitable for industrial furnaces and / or boilers burning pulverized coal. The burner system includes a dual draft regulator to control the combustion air flow, and a burner nozzle that divides the annular pf flow into oxygen-enriched and oxygen-depleted pf flows. This invention relates to furnace and boiler ventilators, and more particularly to ventilator designs for supplying and regulating the air necessary for combustion in industrial furnaces and boilers. The invention relates to the design of ventilation regulators for coal, oil or gas steam power boilers. Background technique [0002] Vent regulators are known to regulate a variety of sources of combustion air. State-of-the-art draft regulators can regulate primary, secondary and tertiary combustion air and can deliver air to the boiler in a variety of ways. Combustion air generally falls into two broad categories, although the invento...
