A heating system utilizing waste heat from illuminating device includes at least one illuminating device and a water supply device. The illuminating device has at least one light-emitting module, which has one side in contact with at least one heat-dissipation device. The heat-dissipation device and the water supply device are connected to each other via a pipeline. Water is supplied by the water supply device to the heat-dissipation device for directly absorbing heat that is transferred from the light-emitting module to the heat-dissipation device and accordingly cooling the heat-dissipation device. The heat-absorbed water is then delivered via the pipeline to a water reservoir for people to use. Thus, waste heat produced by the illuminating device is effectively converted into a usable energy source to be fully utilized.

Energy recovery in hot strip mills by converting the cooling heat of the continuous casting plant and the residual heat of slabs and coils into electrical enery or otherwise utilizing the captured process heat

Номер: US20120118526A1
Автор: Axel Stavenow, Horst Gaertner, Juergen Seidel, Peter Sudau
Принадлежит: Sms Siemag AG

In hot strip plants, after casting, the residual heat of a partial quantity of the slabs has hitherto been used such that the slabs either are directly rolled or are placed warm or hot in the furnace. The remaining slabs normally cool after casting in a hall through which flows air and are stacked before their further transport. The same applies to the residual heat present in the coils after winding, which often cool in the coil-storage area in air. The cooling energy of the continuous-casting plant likewise escapes unused into the surroundings. In order to convert this unused solidification heat and residual heat into electric energy, it is proposed according to the invention that the slabs ( 10 ) are cast in a continuous-casting plant and the slabs ( 10 ) or coils are transported into the slab-storage area ( 12 ) or coil-storage area and during the casting in heat exchangers ( 31 ) and/or during the transport in heat exchangers ( 31 ) heat is extracted and/or there are deposited in part one on top of the other in specially prepared storage areas ( 30 ) provided with heat exchangers ( 31 ) for a short time or several hours, wherein in this transport period the cast billet or the slab ( 10 ) and/or in the storage period the residual heat of the slabs ( 10 ) or coils is transferred via heat conduction and thermal radiation and convection via the heat exchangers ( 31 ) into a heat-transfer medium such as, for example, thermal oil, and heats it, which then is discharged via heat-transfer transport lines ( 33 ) for power generation and/or direct use of the process heat by other heat consumers.

Принадлежит: TINMAN Inc

Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.

A closed-loop, solid-state system generates electricity from geothermal heat from a well by flow of heat, without needing large quantities of water to conduct heat from the ground. The present invention contemplates uses for depleted oil or gas wells and newly drilled wells to generate electricity in an environmentally-friendly method. Geothermal heat is conducted from the Earth to a heat exchanging element to heat the contents of pipes. The pipes are insulated between the bottom of the well and the surface to minimize heat dissipation as the heated contents of the pipes travel to the surface.

The purpose of the present disclosure is to solve the problems of a difficult operation or occurrence of corrosion damage to equipment caused by the attachment of ammonium sulfate salt, which is generated when unreacted ammonia (NHslip) and sulfur trioxide (SO) in exhaust gas are bonded with each other when a selective catalytic reduction (SCR) is used to eliminate nitrogen oxides that are contained in the exhaust gas generated during the combustion of a boiler or the like, to a heat exchanger of an air preheater (APH) or the like installed at the rear of an SCR device and blocks a passage of the exhaust gas such that the pressure inside the boiler is increased. To this end, a dry ice cleaning device is installed at the front of an exhaust gas inlet in an air preheater such that the blocking of a heat exchanger caused by ammonium sulfate salt or the like is removed by spraying dry ice pellets, and at the same time, high-temperature steam spraying device is installed at a cold end of the air preheater so as to spray the steam in the same direction as that of air supplied to a boiler, thereby removing contaminants more effectively. Furthermore, in order to effectively prevent blocking which occurs in a cold end of the air preheater, dry ice is sprayed to the front of an exhaust gas inlet of the air preheater and also, to the front of a supply air inlet of the air preheater which is an opposite direction thereof, such that a cleaning effect is increased. 1.
