    摘要： A sectional heat exchanger comprises a plurality of aluminum cast segments; means clamping the aluminum cast segments to each other, thereby assembling the plurality of aluminium cast segments vertically side by side; and sealing means between neighbouring aluminum cast segments. The sectional heat exchanger comprises a combustion chamber extending through the plurality of aluminum cast segments. The combustion chamber is configured for the installation of a premix burner. The heat exchanger comprises a plurality of flue gas flow channels extending from the combustion chamber. At least part of the flue gas flow channels are provided between each two neighbouring aluminum cast segments. Each aluminum cast segment comprises at least one fluid flow channel for heating fluid by heat transfer from the flue gas flowing through the flue gas channels. The aluminum cast segments comprise a set of lugs, wherein all lugs of the set of lugs are aligned with each other. The clamping means comprise a bolt and nut connection. The bolt extends through lugs of the set of lugs of only two neighbouring aluminium cast segments. The lugs through which the bolt extends contact each other. The bolt and nut connection presses the two neighbouring aluminum cast segments to each other. The clamping means comprise a tie rod extending through lugs of the set of lugs of at least three of the aluminum cast segments thereby pressing the at least three aluminum cast segments to each other.

    摘要： A gas premix burner is provided that comprises - a perforated plate, a woven wire mesh or expanded metal sheet; - a fiber based burner deck placed onto said perforated plate, woven wire mesh or expanded metal sheet; and - an ionization pen to measure the ionization current in the flame of the gas premix burner. The fiber based burner deck is thicker in at least part of the region where the ionization pen is located compared to other regions of the fiber based burner deck. The invention allows to use ionization current measurement for burner control over a broader load range of the gas premix burner.

    摘要： modular flare stack (100) for combustion of combustible fluids comprises a gas feed pipe (101) and at least two burner elements (120) for combustion of the combustible fluids. This modular flare stack comprises an automated control system (190) for fixed stoichiometric combustion applied to air/gas venturi mixing system, based on feedback loop from flue gas temperature. Mixing ratio's are obtained either using a fan for gas flows at lower pressure (less than 0,5 barg), either using a venturi for gas flows at higher pressure (more than 1 barg). The control system also determines the number of operational burner elements and which burner elements are operational. The flare stack of the invention provides premixed surface burners for waste gas streams, guaranteeing extremely low emissions and high destruction efficiency by complete combustion with a high turndown ratio.
