IPC: F23G5/30
Filed: 2011-09-30
Abstract: To reduce nitrogen oxide emissions and corrosion in a bubbling fluidized bed boiler that burns biofuel or waste, air is supplied into the boiler furnace (1) in stages so that two sub-stoichiometric combustion zones (I), (II) and a superstoichiometric zone (III) are brought about. The first combustion zone (I) begins from the height level of primary air supply nozzles (3) and it extends above the fluidized bed (2), ending under the height level (hS) of secondary air nozzles (6). The second combustion zone (II) begins from the height level (hS) of the secondary air nozzles (6) and ends under the height level (hT) of tertiary air nozzles (7). The third combustion zone (III) begins from the height level (hT) of the tertiary air nozzles. The length of the first combustion zone (I) is optimized by placing the secondary air nozzles (6) at a height (hS) from the top surface of the fluidized bed (2), which height (hS) is chosen according to a given calculation formula and calculated according to furnace-specific variables, reference values and design point-specific variables. The design point-specific variables are different in a boiler with a high furnace load and in a boiler with a low furnace load.

Abstract: 1,050,928. Friction clutches. TWIN DISC CLUTCH CO. May 27, 1965 [May 28, 19641, No. 22497/65. Heading F2C. A friction clutch is rapidly and lightly engaged by a small diameter piston having a flexible flange engaging the clutch pressure plate to give soft engagement, full engaging pressure being applied by a large diameter moving cylinder. As shown clutches 35, 36 are selectively engageable to connect gears 44, 45 to a shaft 1 by similar hydraulic actuating means comprising a common cylinder 7 slidable on a piston 2 fixed to the shaft 1 and pistons 20, 21 being slidable on hubs 8a, 9a of the cylinder 7 and having resilient flanges 20b, 21b engageable with the pressure plates of the clutches. Considering the right-hand clutch, when the clutch is disengaged chambers 21a, C2 associated with the piston 21 and cylinder 7 are maintained full of liquid by lubricating fluid supplied through passages 50, 54 in the shaft 1 to a groove 56 in the cylinder hub 9a, whence it flows to the chamber 21a through a passage 58 in the hub and a non-return valve 61, and to the chamber C2 through a clearance 65 between the hub and the shaft 1. Groove 56 is open to exhaust through passages 71, 70 in the shaft, thus preventing build-up of pressure in the chambers. To engage the clutch pressure fluid is supplied through the passages 70, 71 to the chambers, the relatively unrestricted flow to the chamber 21a giving light engagement of the clutch 36 with deflection of the piston flange 21b to give smooth engagement. The supply fluid to the chamber C2 subsequently moves the cylinder 7 to the right, causing the valve 61 to close so that the full apply force is applied to the clutch plates. Liquid can leak from the chamber 21a past a seal 25 between the piston and the cylinder hub so that the cylinder moves slowly until it abuts the piston 21. In a modification the actuating oil pressure and lubricating oil pressure are supplied directly to the chamber C2 which is in communication with the chamber 21a through the passage 58 and non-return valve 61.

Abstract: 1,226,502. Ignition systems; timing ignition. COMPAGNIE DES COMPTEURS. Jan. 27, 1969 [Jan. 25, 1968; Nov.21, 1968], No.4497/69. Heading F1B. The element 100 which may be of the electromechanical or electronic type is connected to the circuit 101 thus enabling the signals coming from the element to be shaped. The circuit 102 is responsible for generating and defining a timebase. The timebase is obtained by variable timing arrangements involving in particular the capacitors 121 and 122. The capacitor 121 has one charging time constant and two discharge time constants. The circuit 103 is a voltage threshold device controlled by the signal coming from the capacitor 122 in order to produce an output signal which generates the ignition spark. At all times the transistor 149 supplies a collector current proportional to the voltage across the terminals of the capacitor 121 . The resistance of the resistor 151 can be made a function of the vacuum in the induction manifold. On completion of the discharge of the capacitor 122 the transistor 141 goes into saturation, thus discharging the capacitor 155 across the resistor 157 and blocking the transistors 156, 158 and 159 so that the primary coil current is cut off. The duration of the spark corresponds to the time of discharge of the capacitor 155 and can decrease with rising speed.

A method for replacing the carrying and balancing cables in a multi-cable lifting device for a pit comprises using the driving drum 1 of the lifting device for hauling up old cables and lowering new cables, the cables being handled being wound twice on the drum 1 for gripping purposes, once under and once over pressing roller chains 3 adjacent the periphery of the drum 1. A chain 3 having appropriately profiled rollers is provided for each cable of the multicable group. For replacing the carrying cables, the latter are clamped at 4 to support the lower cage I and are disconnected from the upper cage II which is supported on beams, and the free ends of cable are passed around the outside of the roller chains 3, over a pulley 2, between the chains 3 and the drum 1, over another pulley 5 and on to a spool 7. After freeing the clamp 4 and disconnecting the balancing cables from the lower cage I, the latter is lifted up and supported on beams alongside the cage II, whence the carrying cables are disconnected from the cage 1 and spooled out of the system. The reverse procedure is adopted for installing the new carrying cables. For replacing the balancing cables, once they are hanging loosely from the upper beam supported cage II, they are clamped at the top of the pit and then disconnected from the upper cage II whereupon they are spooled up in the same way as the carrying cables. The embodiment of Fig. 4 (not shown) shows an arrangement where the driving drum is situated directly over the pit.
