摘要:
An improved staged combustion method useful with oxy-fuel combustion and in a furnace which contains a charge, wherein substoichiometric combustion and low velocity injection of fuel and primary and secondary oxidant are carried out in an orientation which forms a reducing atmosphere proximate the charge surface.
摘要:
The efficiency of selective non-catalytic reduction reactions for converting NOx in a flue gas to molecular nitrogen is improved by producing the flue gas from combustion of fuel with oxidant having an oxygen concentration above that of air.
摘要:
A green sheet coating material includes ceramic powder and a binder resin containing a butyral based resin as the main component, which furthermore includes a xylene based resin as a tackifier. The xylene based resin is included in a range of 1.0 wt % or less, more preferably 0.1 or more and 1.0 wt % or less, and particularly preferably more than 0.1 and 1.0 wt % or less with respect to 100 parts by weight of ceramic powder.
摘要:
A process for removing blisters (large bubbles in a glassmelt) and seeds (small bubbles in a glassmelt) from a glassmelt by feeding helium bubbles having a diameter between about 0.5 cm and about 3 cm at a prescribed flow rate and location to effectively produce a substantially bubble-free article.
摘要:
A furnace is heated by a burner that can be selectively operated by either air-fuel or oxy-fuel combustion. The burner comprises a conduit for fuel, a conduit for air, a conduit for oxidant, and control means for regulating flow through the air and oxidant conduits. An air-fuel fired furnace can be modified by addition of the oxidant and fuel conduits and the control means for regulating flow through air and oxidant conduits.
摘要:
Heat in a stream of combustion products obtained from a glassmelting furnace heated by oxy-fuel combustion is passed to incoming glassmaking materials in a heat exchanger without requiring reduction of the temperature of the stream yet without causing softening of the glassmaking material.
摘要:
A driver unit 2 for striking out a staple, and a clincher unit 3 for clinching of legs of a staple are separated vertically from each other. The driver unit 2 and the clincher unit 3, respectively, are provided with drive motors M1, M2. Encoders 21, 40 are formed on respective drive shafts 12, 30, which drive the driver unit 2 and the clincher unit 3, to generate pulse signals P1, P2 upon rotation of the respective drive shafts. A control device 47 inputs thereinto the pulse signals P1, P2 to count the same, and the respective drive motors M1, M2 are controlled by the control device 47 on the basis of count values.
摘要:
A system and method detect symbols of a modulated signal received via a plurality of channels of a wireless communications system. A symbol transmitted via the channels is initially estimated based on the channel estimate from either pilot symbol or previously estimated symbol, and then channel estimate is updated. The next estimate of the symbol is computed by using updated channel information and maximizing the expectation of the log likelihood function. The next estimate is then quantized according to the signal constellation. The quantized estimate of the symbol is compared with the previous estimate of the symbol to determine if the previous estimate of the symbol and the quantized next estimate of the symbol have converged. Otherwise, the quantized next estimate of the symbol is made as the input for the next iteration, and the updating, optimizing, quantizing, and comparing are repeated until the estimate converges.
