Abstract

The invention provides a combustion barrel and a fuel oil and fuel gas boiler. The combustion barrel comprises a combustion outer barrel body, a combustion middle barrel body, a combustion inner barrel body and a heat preserving and heat insulating barrel body; the combustion middle barrel body is fixedly arranged in the combustion outer barrel body; the combustion inner barrel body is fixedly arranged in the combustion middle barrel body; and the heat preserving and heat insulating barrel body is fixedly connected with one end of the combustion outer barrel body, and a combustion port is formed in the other end of the combustion outer barrel body. The technical scheme is adopted, the hot air utilizing rate of the fuel oil and fuel gas boiler can be effectively increased, and meanwhile theeffects of facilitating installing, disassembling and maintaining, preventing explosion and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of fuel gas boiler equipment, and in particular relates to a combustion tube and a fuel gas boiler. Background technique [0002] Oil-fired gas-fired boilers refer to boilers that can use both fuel oil and gas; the existing oil-fired gas-fired boilers have the following technical defects: they cannot be inspected and repaired after problems occur inside the boiler; due to the limitation of the furnace structure, the shape of the flame cannot be fully expanded, Insufficient combustion; high-temperature flue gas directly scours the opposite furnace wall or base tube plate, which is likely to cause local overheating damage; the flue gas flow is short, the residence time in the furnace is insufficient, the heat is not fully utilized, the exhaust gas temperature is high, and The thermal efficiency is low; and the existing boiler will form a large internal pressure during the combustion and heating process, which ...
