Internal combustion long-term thermal insulation multi-layer heating boiler

Abstract

The invention belongs to the field of boilers, and particularly relates to an internal combustion long-acting insulating multi-layer heating boiler solving the problems that in the prior art, the energy saving and environment protection comprehensive effects are poor, and the combustion effect of a boiler is not good. A hot water layer is arranged on a boiler outer shell and a boiler furnace outer layer. The interior of a boiler furnace is divided into an upper part and a lower part, the upper part is a heat exchange chamber, and the lower part is a boiler furnace heating chamber. The boiler furnace heating chamber is formed by a boiler furnace heating chamber outer shell and a boiler furnace heating chamber inner shell. A combustion chamber and a high-temperature heating chamber are arranged between the boiler furnace heating chamber outer shell and the boiler furnace heating chamber inner shell. An outlet of the combustion chamber and an outlet of the high-temperature heating chamber are communicated through two chamber communicating pipes. A boiler furnace inner heat exchange chamber is formed by an inner cavity of the boiler furnace heating chamber inner shell. A heating chamber heat exchange pipe bundle is arranged in the boiler furnace inner heat exchange chamber. A vertical heating chamber heat exchange pipe bundle is communicated with the upper part and the lower part of the boiler furnace heating chamber inn shell. According to the boiler, methyl alcohol, fuel gas and fuel oil can be combusted, the boiler is suitable for various kinds of fuel, conduction oil is added in the boiler furnace, and long-acting insulating can be achieved.

Description

technical field [0001] The invention belongs to the field of boilers, in particular to an internal combustion long-acting thermal insulation multi-layer heating boiler. Background technique [0002] At present, the use of boilers in my country generally has problems such as wasting energy, burning black smoke, and environmental pollution. In the prior art, combustion-supported boilers relying on wind power are very common, and the combustion effect is relatively good. The disadvantage is that when the boiler cleans up coke and adds coal, black smoke is emitted. The biggest disadvantage is that it causes waste of energy and serious dust pollution. Less than the national environmental protection requirements. [0003] Gas is a general term for gaseous fuels, which can be burned to release heat for use by urban residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas and biogas. Compared with developed cou...
