The present invention relates to a cooling device for preventing fire due to spontaneous combustion of coal stockpiles in a coal-fired power plant, and more specifically, to a cooling device for preventing spontaneous combustion of coal stockpiles, for which a plurality of cooling devices are provided at a predetermined interval in coal stockpiles and, when a temperature (ignition temperature) specified by a user is detected from the outer surface, compressed liquefied nitrogen stored in the cooling device is ejected to lower a temperature around the loaded coal, thereby preventing spontaneous combustion by the oxidation of coal.

A pressure vessel includes a pump having a passage that extends between an inlet and an outlet. A duct at the pump outlet includes at least on dimension that is adjustable to facilitate forming a dynamic seal that limits backflow of gas through the passage.

The present invention relates to a humidity detection-based pellet grill control method and a feeding system of a pellet grill, where the pellet grill is energized so that the feeding system thereof and a humidity sensor on the feeding system are in an energized state; and the humidity sensor is used to continuously monitor humidity of a fuel conveying channel of the feeding system in which a pellet fuel has been stored, so that a controller determines humidity level of a space environment or the pellet fuel in the fuel conveying channel. This can prevent the fuel that has become powdered due to moisture from drying into hard lumps again in the fuel conveying channel which can result in blockage of a screw conveyor, thus protecting the feeding system and reducing maintenance costs.

A ground supported single drum power boiler is described combining a refractory lined and insulated V-Cell floor; refractory lined and insulated combustion chamber; integrated fuel chutes configured to pre-dry wet solid fuel; top mounted fuel bin; internal chamber walls; configurable combustion air systems; and a back pass with after-burner ports and cross flow superheaters. The boiler can be configured in pre-assembled modules to minimize the field construction time and cost. An alternative embodiment is adaptable as a gasifier.
