INJECTOR NOZZLE ASSEMBLY FOR GAS FLOW ADJUSTMENT AND COOKING EQUIPMENT COMPRISING SAID INJECTOR NOZZLE ASSEMBLY. The present invention relates to an injector nozzle assembly for gas flow adjustment, in particular, designed to enable the conversion between natural gas (NG) and liquefied petroleum gas (LPG) in a quick and simplified manner, as well as cooking equipment equipped with said injector nozzle assembly. The injector nozzle assembly comprises: a gas spray structure (1); a first injector nozzle (2) equipped with a first opening (21) for gas passage, the first injector nozzle (2) being interchangeably associable with the gas spray structure (1); and a second injector nozzle (3), interchangeable with the first injector nozzle (2), the second injector nozzle (3) having a second opening (31) communicating with the first opening (21) of the first injector nozzle (2), wherein the area of the first opening (21) and the area of the second opening (31) are different from each other. The cooking equipment comprising the said injector nozzle assembly is installed immediately before the burners, so that the user can assemble and disassemble the second injector nozzle (3) from the first injector nozzle (2) and assemble and disassemble the first (...).

A nozzle tip for a pulverized solid fuel pipe nozzle of a pulverized solid fuel-fired furnace is provided. The nozzle tip includes an inner nozzle portion and an outer nozzle portion that receives therein the inner nozzle portion. The outer nozzle portion has a lower supporting surface that is configured to support a lower surface of the inner nozzle portion. The outer nozzle portion also includes a plurality of ribs that define therebetween a plurality of flow passages for the passage of air. The ribs, in addition to define the airflow passages, provide bolstering support for the lower supporting surface. The outer nozzle portion is formed from stainless steel.

The invention relates to a gaseous fuel burner (10) with a longitudinal axis (L), particularly for a kiln firing ceramic articles, comprising a tubular body (12) intended to be connected to gas supply means (34), said tubular body (12) housing a circumferential gas flow distributor (20) having first sectors (S1) and second sectors (S2) intended to be connected at the inlet to said gas supply means (34), the first sectors (S1) opening at the outlet into a central channel (23) with a longitudinal axis (L) and the second sectors (S2) opening at the outlet into an annular channel (25) surrounding the central channel (23), wherein the tubular body (12) comprises a radially internal annular outlet surface (19) having a convex curved profile along the longitudinal axis (L).Figure to be published with the abbreviation: [Fig. 1]

一种内置式氨催化热解的煤氨混燃低氮稳燃燃烧器及燃烧方法，包括：同轴套筒式进料燃烧装置、预燃装置以及第一级氨气通道自热催化热解模块；所述同轴套筒式进料燃烧装置包括由内向外同轴布置的中心管、一次风套筒、紧凑型二次风套筒，并包括位于紧凑型二次风套筒外侧且彼此隔离设置的第一级氨气通道、分离型旋流内二次风通道、第二级氨气通道和分离型旋流外二次风通道；所述预燃装置包括预燃室，所述预燃室具有预燃室出口端面和预燃室内侧面，并由高温蓄热耐火结构围成；所述第一级氨气通道自热催化热解模块设置于第一级氨气通道的近出口段。本发明具有协同低氮燃烧、催化模块可维护、自热供热、结构紧凑的特点。

There is provided a gas burner that comprises a surface. The surface forms a burner deck comprising burner deck portions and a separation surface. The burner deck portions have holes. The separation surface is arranged to separate the burner deck portions from each other. The burner deck portions are adapted to define reaction zones extending over the burner deck portions. The holes are adapted to provide gas to be combusted in the reaction zones. The burner deck portions are arranged relative to each other to prevent the reaction zones from extending over the separation surface.

An oil burner 14 has an oil supply interface 102 at a first end and a firing tip 104 at a second end, with the second end including a control pintle 116 arranged to control a flow of oil out of the firing tip. The burner further includes a first oil channel 112 extending from the oil supply interface to the firing tip and a second oil channel 114 extending from the oil supply interface to the control pintle, the control pintle includes a circulation oil channel 120 connecting the second oil channel to the first oil channel, and a non-return valve 118 prevents oil flow from the first oil channel to the second oil channel via the circulation oil channel but permits oil flow from the second oil channel to the first oil channel. In use, the control pintle permits oil to flow from the first oil channel out of the firing tip when a pressure differential between the first oil channel and the second oil channel is positive, and directs oil from the second oil channel to the first oil channel via the circulation oil channel when a pressure differential between the first oil channel and the second oil channel is negative, and thus prevents oil from flowing out of the firing tip. The arrangement renders the burner resistant to oil Stagnation, oil Solidification and oil degradation
