Abstract:
The invention pertains to a premix gas burner for combusting a hydrogen-containing premix burner gas containing a fuel gas containing at least 80 vol% of hydrogen, comprising: - a gas supply chamber to receive the hydrogen-containing premix burner gas, - a burner deck, comprising a metal burner deck plate, having a chamber facing surface and a flame facing free surface, and a plurality of gas outflow apertures extending through the metal burner deck plate allowing hydrogen-containing premix burner gas to flow from the gas supply chamber to a combustion zone adjacent to the flame facing free surface of the metal burner deck plate, wherein the metal burner deck plate is made of a metal having a thermal conductivity coefficient at room temperature of at least 80 W/(mK) and having a Young's modulus at room temperature of 150 GPa or less.
Abstract:
There is provided a premix gas burner system comprising a burner, a mixing chamber, and a control system. The mixing chamber is arranged to receive a flow of air and a flow of combustible gas to create a mixture. The combustible gas comprises at least 80% hydrogen. The burner has a surface forming a burner deck comprising burner deck portions and a separation surface arranged between the burner deck portions. The burner deck portions are adapted to combust the mixture in reaction zones extending over the burner deck portions. The burner deck portions are arranged relative to each other to prevent the reaction zones from extending over the separation surface. The control system is adapted to control the flow of air and the flow of combustible gas to modulate the burner to operate at a minimum load, an intermediate load, and a maximum load.

Abstract:
The invention pertains to a crane, a method for assembly of a crane and a method for disassembly of a crane. In accordance with the method according to the invention, the first mast (10) is fixed in a vertical position. A top mast section (35) of a second mast (30) is positioned adjacent to and outside of the first mast. The top mast section is moved vertically upwards and this movement is guided by a guide system (60). Then, the top mast section is fixed relative to the first mast at a position which is at a larger vertical distance from the crane base (2). Then, a first intermediate mast section (36) of the second mast is fixed to a lower end (35b) of the top mast section to build up the second mast. Then, first intermediate mast section is connected to a pivot (31), and the second mast is pivoted away from the first mast. The crane further comprises a mast section mounting device (70) and a mast section locking device (75) to respectively move the first mast into the vertical position and lock a section of the second mast to a section of the first mast.
Abstract:
A method for eviscerating slaughtered poultry having a carcass (1) with a viscera pack (19) in a body cavity of the carcass, wherein the body cavity has been opened at the vent end. The method comprises: - retaining the carcass in an orientation with the neck end downwards, - entering the body cavity of the retained carcass with an eviscerating tool (40) via the opened vent end, said eviscerating tool having a front end (41), - dipping the eviscerating tool deeper into the body cavity with its front end passing along the breast side (4) of the body cavity so that the front end thereof moves past the viscera pack at least till beyond the liver (15), - withdrawing the eviscerating tool (40) and thereby lifting the viscera pack (19) out of the body cavity. Use is made of a gizzard pre-lifting tool (60;90), distinct from the eviscerating tool (40), which is entered into the body cavity of the retained carcass via the opened vent end, which gizzard pre-lifting tool is operated to grasp the gizzard (14) and/or belly fat (17) bonded to the gizzard and which gizzard pre-lifting too is operated to lift the gizzard thereby entraining a further portion (15,16) of the viscera pack, said lifting of the gizzard being performed prior to the front end of the eviscerating tool passing along the breast side of the body cavity past the liver (15) as the eviscerating tool (40) is dipped into the body cavity.
