An incinerating container for grills and similar broilers. The incinerating container receives products of combustion from a gas burner or hot gases from an electric element or other heat source. Apertures in a top of the incinerating container receive oil into the incinerating container, such as oils from melted fat as food cooks. The oils are incinerated within the incinerating container. The apertures formed in the top allow hot oils to enter the incinerating container for combustion of the oils within the incinerating container, and are constructed to prevent flames from materially exiting the incinerating container.

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 disclosure relates to a gas-heated infrared radiation emitter comprising a burner plate, the burner plate serving as a combustion surface, and a radiating screen positioned on the combustion surface side of the burner plate. The radiating screen is formed by a mesh material or material with open pores, and has an inner face oriented towards the combustion surface side of the burner plate.

The inner surface of the screen comprises at least a first portion and a second portion offset from one another in relation to the combustion surface, such that the distance between the combustion surface and the first portion is less than the distance between the combustion surface and the second portion.

A boiler can have a combustion chamber, a burner, a heat exchanger in fluid communication with the combustion chamber, and a flue for removing a combustion product from the boiler. The burner has a protruding taper shape such as a cone or similar shape. The protruding taper shape of the burner distributes heat to the heat exchanger more evenly than a cylindrical shaped burner thereby reducing heat losses at the combustion chamber wall and increasing the thermal efficiency. The protruding taper shape of the burner also reduces noise associated with the operation of the burner.

A combustion system includes a fuel and oxidant source and a flame holder. The flame holder includes a plurality of discrete slats arranged in parallel defining combustion channels between adjacent slats. Pairs of adjacent slats may be oriented to operate substantially as a V-gutter. The fuel and oxidant source outputs fuel and oxidant into the combustion channels. The flame holder holds a combustion reaction of the fuel and oxidant in the combustion channels.

A combustion plate is for use in a totally aerated combustion burner in which a plate main body made of ceramic has formed therein a multiplicity of flame holes for ejecting a premixed gas. The plate main body is provided, in a lattice shape, with non-flame-hole sections free of flame holes. Each of those sections of the plate main body which are enclosed by the non-flame-hole sections constitutes a collective flame-hole section having formed therein in a crowded manner a plurality of flame holes. Flame holes formed in those peripheral portions of the collective flame-hole sections which are adjacent to the non-flame-hole sections are smaller in diameter than the diameter of the flame holes formed in those portions of the collective flame-hole sections which are inner than the peripheral portions.

Methods and devices for gas mixture combustion on a surface of a permeable matrix are provided which produce or result in surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the matrix surface and decreasing concentrations of pollutant components in the combustion products. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity and configured to preheat the combustible gas mixture as it travels through the matrix. The burner includes a plurality of thermal elements having a thermal conductivity higher than and disposed in thermal transfer communication with the matrix base material. The permeable matrix base material forms a combustion surface with at least a portion of the thermal elements exposed above the combustion surface. The gas mixture is combusted at or near exit pores and channels formed at the permeable matrix material combustion surface.

The present disclosure is directed to systems and methods for low-CO.sub.2 emission combustion of liquid fuel with a gas-assisted liquid fuel oxygen reactor. The system comprises an atomizer that sprays fuel and CO.sub.2 into an evaporation zone, where the fuel and CO.sub.2 is heated into a vaporized form. The system comprises a reaction zone that receives the vaporized fuel and CO.sub.2. The system includes an air vessel having an air stream, and a heating vessel adjacent to the air vessel that transfers heat to the air vessel. The system comprises an ion transport membrane in flow communication with the air vessel and reaction zone. The ion transport membrane receives O.sub.2 permeating from the air stream and transfers the O.sub.2 into the reaction zone resulting in combustion of fuel. The combustion produces heat and creates CO.sub.2 exhaust gases that are recirculated in the system limiting emission of CO.sub.2.

A plate body 11 of a combustion plate 10 is provided with no-burner port portion 13 where no burner ports 12 exist, and a burner port group 14 made up of a plurality of burner ports 12 is arranged in each region 15 of the plate body 11 surrounded by the no-burner port portion 13. A port diameter D of the burner ports 12 differs between the burner port groups 14, but the respective burner port groups 14 are made up of the burner ports 12 of the same port diameter D, and are arranged so that the greater the port diameter D of the burner ports 12 making up each burner port group 14, the greater the interval T between the burner ports 12 in the burner port group 14 becomes.

The invention relates to a process burner for combustion of a plurality of fuel gases with a gaseous auxiliary medium, wherein one of the fuel gases comprises carbon monoxide (CO). The process burner according to the invention includes a first fuel gas unit, a second fuel gas unit and an auxiliary media unit. A first fuel gas which may be natural gas for example is introduced into the process burner via a first fuel gas nozzle in the region of the combustion zone. Carbon monoxide-containing fuel gas is introduced into the process burner via the second fuel gas unit, wherein a second fuel gas nozzle for introducing the carbon monoxide-containing fuel gas is arranged in the region of the auxiliary media unit.
