Provided are a pulverized coal boiler with a bottom combustor, and a control method for the pulverized coal boiler, wherein the pulverized coal boiler includes a furnace, at least one bottom combustor and a secondary air distributing device. Each combustor is provided with a combustor spout, and the secondary air distributing device surrounds the combustor and is arranged at the bottom of the furnace. The secondary air distributing device includes an internal secondary air distributing device and an external secondary air distributing device, wherein the internal secondary air distributing device includes an internal secondary air gathering box and an internal secondary air pipe, and the external secondary air distributing device includes an external secondary air gathering box and an external secondary air pipe.

A flameless combustor usable with multiple fuels comprises a combustion chamber and fuel lines in communication with the chamber.

An apparatus and method that enables a single person to remove and replace a part, for example a burner housing, from an industrial piece of equipment such as oilfield equipment. A base of the apparatus attaches, either removeably or permanently, to a portion of the equipment such as an exhaust stack, that is above the part. The apparatus has a plurality of arms which swing out from the base, including a beam which is rotated to be aligned with the part. Straps attached to the beam are tightened around the part, and the arms are then extended to remove the part from the equipment.

Methods and systems for de-stabilizing foam produced in submerged combustion melters. A molten mass of glass and bubbles is flowed into an apparatus downstream of a submerged combustion melter. The downstream apparatus includes a floor, a roof and a wall connecting the floor and roof, but is devoid of submerged combustion burners and other components that would increase turbulence of the molten mass. The molten mass has foam on at least a portion of a top surface of the molten mass. One method includes directly impinging an impinging composition onto at least a portion of the foam in the downstream apparatus. Systems for carrying out the methods are described.
