Device and method for heating furnaces by means of radiant tubes
To heat a furnace chamber (16) indirectly using radiant tubes (11) to (14), heating energy is transferred through the radiant tube wall into the furnace chamber (16). During steady-state operation, the temperature in the radiant tube (11) to (14) and on its surface is higher than the furnace, depending on the specific heat output of the radiant tube (11) to (14). At a furnace temperature of 770° C. and a heat output of 50 kW/m2, the radiant tube has a temperature of 900° C. The radiant tube (11) to (14) can thus operate continuously with flameless oxidation at this output, even though the temperature in the furnace is only 100° C. However, if the radiant tube (11) to (14) has cooled to the furnace temperature of 770° C. during a break in burning, deflagration is avoided when the associated burner is ignited by initially operating said burner with a flame for a few seconds. |

Vertical slip form construction system with multi-function platform, and method of constructing a building therewith
A method of constructing a building includes attaching a first portion of a roof structure to the yokes of a vertical slip form system. A derrick crane is positioned on top of the first portion of the roof structure. A vertical support core of the building is then formed with the vertical slip form system. The first portion of the roof structure and the derrick crane are raised with the vertical slip form system. The vertical slip form system is removed from the formed vertical support core of the building, and the first portion of the roof structure is then moved into a final position and attached to the vertical support core. The remainder of the roof structure and subsequent floor plates may then be constructed at ground elevation, raised into place, and attached to the vertical support core in a top-down, descending order. |

Metal joint and panel joining method
A metal joint for joining, to a frame built by appropriately combining a horizontal structural member and a vertical structural member, a rectangular panel fitted into the frame includes a base member made of a rectangular metal plate, and cylindrical members which are each made of a metal cylinder, and are fixed onto opposite surfaces of the base member. The base member is adapted to be disposed between the frame and the panel. The cylindrical members are adapted to be fitted into circular holes formed in the frame and the panel. |

Module for realizing modular building structures
A module for realizing modular building structures comprises a bearing block having pairs of flat faces with complementary shaped joints for coupling with further similar modules arranged in side by side position, means for anchoring the bearing block to bearing blocks of side-by-side modules for realizing the building structure. The anchoring means comprise one pair of passages mutually perpendicular and staggered along a first transverse direction, the passages extending in the block from respective flat faces. The anchoring means also comprise reinforcing bars adapted to be inserted in a pair of consecutive passages belonging to two mutually side-by-side modules to define a reinforcement meshed armor. Each bar has ends associated with male and female connecting elements for coupling with facing ends of contiguous bars belonging to a side-by-side module. |
