A biochar apparatus and a related biochar module may have a horizontal table-shaking mechanism and a tapered channel for causing biochar pieces generated in a firebox to fall through openings in the table to a conveyor system below. The table may be configured with replaceable grate panels. A quenching reservoir pan for holding quenching liquid receives a drainage basket at a discharge end of the conveyor system for quenching hot pieces of biochar and allowing easy retrieval of the quenched pieces.

A ground supported power boiler is described combining a refractory lined and insulated conical floor; an insulated cylindrical combustion chamber; a cylindrical furnace with water tube wall; a rectangular convective section; a single vertical steam drum; tangential injection of the fuel and combustion air; means for fluidizing the fuel bed; means for selectively stripping particulates from the flue gases; multi-stage particulate stripping and filtering from flue gases, means for using the walls of steam drum as steam/water droplet separator, means for recirculating and capturing heat from the flue gases; means for pressurizing the interior of the boiler above atmospheric pressure; means for heating and drying fuel prior to feeding the fuel to the boiler; means for creating hydrogen shift reaction; means for eliminating any need for sootblowing; and designed to not require the use of an induced draft fan.

The invention relates to a burner for gaseous, fluid or powdery fuels, into which three components are introduced: a fuel (40); an oxidizing gas (10), for example air; and an inert gas (20), for example gases produced by combustion, nitrogen or water vapor. Two components, for example, air and inert gas, are mixed together and propelled by at least one injection stage (95) arranged at different positions in relation to the movement of the fuel.

The invention relates to a device for, in particular low-emission, burning of (solid) fuels, in particular with visible fire, preferably a fireplace and/or stove and/or stove fireplace, comprising a section for receiving a bulk material, preferably an air turbulence chamber, which is designed for the purpose of guiding an air mass flow in at least one direction through the bulk material; and receiving the bulk material in such a way that the air mass flow experiences turbulence through the bulk material, the turbulence slowing down the air mass flow along the at least one direction, and making the air mass flow slowed down in this way available for burning of the (solid) fuel, in particular such that the burning is carried out with little particulate matter.

Apparatus to produce biomass charcoal (120) which can be inserted in a container whose section orthogonal to an axis (S) is subject to the specific application; the apparatus comprises an external casing (12, 12), associated internally with at least a tubular body (14, 14) located coaxial to create at least one interspace (16, 16) for the passage of primary air (A1) in which at least a support plane (34) is housed able to support the biomass (100) and able to allow a flow of primary air (A1) to feed the biomass (100), the tubular body (14, 14) has a pipe (55) for the passage of secondary air (A2) provided with a hole (15) in correspondence with its lower end and has exit means (22, 22) of the secondary air (A2) disposed in correspondence with an upper end coordinated with a plate (24, 24).

The present invention relates to an ignition device using pellet fuel capable of quickly igniting and burning the pellet fuel, which is supplied into an inner container, and including a container part having the inner container in which the pellet fuel is accommodated while being dropped therein and an outer container of which an upper part is integrally provided with an outer side of the inner container, a heater bar provided at a lower part of the container part and configured to ignite the pellet fuel while being heated by electrical energy, and a cover provided at an inner bottom of the inner container and configured to cover the heater bar.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a lid, a cooking chamber, an engine, and one or more processors. The lid is movable between a closed position and an open position. The engine is configured to output heat to the cooking chamber. The one or more processors are configured to detect a closing movement of the lid. In response to detecting the closing movement, the one or more processors are configured to command the engine to operate in an increased output mode that increases the heat output of the engine.
