Energy-saving high-efficient gas normal-pressure boiler

Abstract

The present invention relates to a gas boiler, and particularly to an energy-saving high-efficient gas normal-pressure boiler. The energy-saving high-efficient gas normal-pressure boiler of the invention settles the problems of large gas consumption, insufficient burning, low thermal efficiency and inferior durability existing in the prior gas boiler. The energy-saving high-efficient gas normal-pressure boiler comprises the following components: a boiler housing, a fire tube, an inner container of a hearth, an outer container of the hearth, an inner face plate, the hearth surrounded by the inner container of the hearth, a water interlayer which is surrounded by the fire tube, the inner container of the hearth, the outer container of the hearth and the inner face plate, a first vortex combustion chamber and a second vortex combustion chamber that are respectively provided at the front end and the back end in the boiler housing. The fire tube is sleeved with a water tube with both ends communicated with the water interlayer. The two ends of the water tube are provided with the outer face plates which have edges fixed with the side wall of the inner container of the hearth and are used for supporting the water tube. The energy-saving high-efficient gas normal-pressure boiler of the invention reduces the gas consumption amount while increasing the usage factor of the heat energy of the fuel, and is a novel gas boiler which has the advantages of energy saving and environment protecting.

Description

technical field [0001] The invention relates to a gas-fired boiler, in particular to an energy-saving and high-efficiency gas-fired atmospheric boiler. Background technique [0002] With the development of society and the enhancement of people's energy-saving awareness, the energy-saving transformation of gas-fired boilers is imperative. Due to the limitation of its own structure, the existing gas-fired boilers generally have the problems of large gas consumption, insufficient combustion and low thermal efficiency; the existing gas-fired boilers mainly include a furnace shell, a furnace inner tank, a furnace outer tank, and The finished furnace has fire tubes arranged in parallel axially between the inner tank of the furnace and the outer tank of the furnace. The two ends of the fire tube are fixed with an inner flower plate whose edge is fixed to the side wall of the inner tank of the furnace. The front and rear ends of the furnace shell are The first vortex cyclone combus...
