A device to facilitate and maintain a fire, having a camera assembly with a base, an apex, lateral columns, a first ring, and a second ring; and an air intake channel connected to the camera assembly. The first and second rings are intercepted by the lateral columns to define a plurality of apertures. The camera assembly defines a cavity area. The cutouts are positioned around the base separated a predetermined distance from each other, and extend from the base bottom edge without reaching the base top edge. The main opening extends from the base bottom edge towards the base top edge. The main opening defines a semi-circle. The plurality of apertures defined at the camera assembly and air intake through the air intake channel provide a sufficient amount of oxygen so that a fire is maintained until matter upon the camera assembly is consumed without suffocating and become extinguished.

The disclosed technology includes a device for extending the turndown ratio of a gas-fired burner system. The device can comprise a variable area device configured reduce the amount of fuel and air passed to the burner during low output conditions by adjusting the cross-sectional area of the passage between the blower and the burner. The variable area device can be controlled by an actuator that adjusts the position of the variable area device. The actuator can be manually controlled, mechanically controlled, or electronically controlled.

Some embodiments of the disclosure provide a steam generator and a car washer with the steam generator. The steam generator includes: a boiler having a combustion chamber. The steam generator further includes: a windproof cover, at least a part of an ignition device of the steam generator being located in the windproof cover; an igniting cover, at least a part of the igniting cover being located in the combustion chamber, and an outlet of the windproof cover being located in the igniting cover; an air inlet grating, the air inlet grating being provided around the windproof cover and connected with the windproof cover, and the air inlet grating being located on an inner side of an air inlet of the igniting cover, to prevent airflow in the igniting cover from flowing out from the inlet of the igniting cover.

A combustion system includes a premix blower system and the premix blower system includes an additional air inlet with an adjustable opening which includes an additional reversibly pluggable air intake. The adjustable opening of the additional air inlet can be opened at higher elevations to compensate for thinner air.

An apparatus for cooking, a cooking appliance monitoring system, and a method of monitoring a cooking appliance are provided. The monitoring system collects and processes signals from sensors linked to the cooking appliance. Further, the monitoring system determines attributes of parameters associated with the cooking appliance and stores the attributes in a cloud-based system and stores the metadata about the attributes in a blockchain.
