IPC: G01N21/31
Filed: 2011-12-05
Abstract: A method for measuring alkalihalide content of flue gas. The method comprises generating a light beam (170), wherein the light beam (170) comprises photons having a first wavelength (lambda1), guiding the light beam (170) to a first optical path (160), wherein the first optical path (160) runs through a space (110) containing the flue gas, whereby the light beam (170) is attenuated to an attenuated light beam (175) and detecting a first value indicative of a first intensity (Ik0) of the attenuated light beam (175). The method further comprises generating a light pulse (710), wherein the light pulse (710) comprises photons having a second wavelength (lambda2), dissociating at least part of the alkalihalide molecules (510) on the first optical path (160) to alkali atoms (520) and halogen atoms (525), using the light pulse (710), wherein the light beam (170) is further attenuated to an attenuated light beam (175) by absorption to the alkali atoms (520) on the first optical path (160), detecting a second value indicative of a second intensity (Ik) of the attenuated light beam (175), and determining, using the first value and the second value, the alkalihalide content of the flue gas. Furthermore, a device (990) for measuring alkalihalide content of flue gas by performing the method. Still further, a boiler (100) comprising the device (990).

Abstract: In the method and system of establishing a trusted relationship, first a virtual private network is established between a key device and at least one locking device. Thereafter, in order to establish a trusted relationship the key device sends a message encrypted with its private cryptographic key to at least one locking device. The message comprises the certificate of the trusted key device and the certificate of some other device, with which the locking device that received the message shall establish a new trusted relationship. By using the established trusted relationship either a trusted relationship between the locking device and a new key device or a trusted relationship between two or more locking devices is established, whereby a virtual private network can be established between the locking devices.

Abstract: 1,251,194. Furnace tapholes. FREEMAN CORP. 19 Nov., 1968, No. 64911/68. Heading F4B. [Also in Division C3]  Tapholes in metallurgical furnaces are sealed by a composition which comprises an inert binder, metallic iron powder and other finely divided combustible metallic particles. The metallic particles may be of a ferro-aluminium alloy, a ferro-silicon alloy or a ferro-aluminiumsilicon alloy which preferably have a size smaller than 100 mesh (U.S. standard screen) with 30% by weight or more capable of passing through a 325 mesh. The iron powder preferably constitutes 1/3-4/5 of the weight of the iron powder and the alloy constituent whilst the binder preferably makes up 5-50% of the total weight of the composition. The binder may be clay or a coal tar pitch. In addition when the binder does not itself render the composition as plastic as is desirable or necessary a plasticizing agent, such as bentonite clay, in a preferred amount from 2-10% by weight, of the composition may be added. The taphole may be plugged with the moulding material alone or a hollow iron or steel pipe containing the mouldable composition may be placed in the taphole. At operating temperatures the composition is converted into a hardened mass which will not ignite or burn on contact with pure oxygen at the exterior of the furnace. The furnace having a taphole sealed in this way can be unstopped by applying to the composition in the taphole or in the pipe oxygen under pressure whereby the composition is ignited and when molten is blown out of the taphole or pipe.
