A hot water boiler and/or hot steam generator as well as a gas burner and a water vessel for the hot water boiler and hot steam generator are disclosed. The water boiler or hot steam generator includes a water vessel which includes an elongated flue pipe which is preferably convoluted and which is fully submerged in the water to be heated during normal operation so that the generated heat is distributed along the flue pipe which is also the gas combustion chamber and can be efficiently dispersed into the water surrounding the flue pipe. This invention also describes a gas burner having an elongated body whose internal aperture increases along its length to create a venturi effect to improve combustion of the fuel gas mixture.
La présente invention concerne une chaudière à eau chaude et/ou un générateur à vapeur chaude ainsi qu'un brûleur à gaz et un contenant à eau pour la chaudière à eau chaude et le générateur à vapeur chaude. La chaudière à eau chaude ou le générateur à vapeur chaude comprend un contenant à eau muni d'un tuyau de raccordement allongé qui est préférablement en spirale et qui est entièrement en immersion dans l'eau à chauffer pendant l'exploitation normale de façon à distribuer la chaleur générée le long du tuyau de raccordement qui est aussi la chambre de combustion à gaz et qui peut être dispersée efficacement dans l'eau entourant le tuyau de raccordement. La présente invention porte aussi sur un brûleur à gaz doté d'un corps allongé dont l'ouverture interne augmente le long de sa longueur pour créer un effet Venturi afin d'améliorer la combustion du mélange gazeux combustible.
