Multifunctional, efficient, energy-saving and environment-friendly boiler for both heating and steaming

Abstract

The invention discloses a multifunctional, efficient, energy-saving and environment-friendly boiler for both heating and steaming. The boiler is provided with an inner shell and an outer shell. The inner shell is sleeved with the outer shell and connected with the outer shell through a support. An interlayer between the inner shell and the outer shell is filled with heat insulation materials. The inner shell is internally provided with a boiler chamber. An interlayer between the inner shell and the boiler chamber forms a water tank. A water inlet pipe, a water draining pipe and a steam guiding pipe are arranged on the side of the outer shell, wherein the water inlet pipe is communicated with the water tank, and the water draining pipe is provided with a control valve. Grate bars are arranged inside the boiler chamber. A smoke guiding pipe is communicated with an inner cavity of the boiler chamber, penetrates through the water tank and is arranged on the upper side of the boiler chamber. The upper end of the inner shell and the upper end of the boiler chamber are sealed. A coal throwing inlet, a flame observing opening and a slag outlet are sequentially formed in one side of the outer shell from top to bottom, wherein the coal throwing inlet, the flame observing opening and the slag outlet penetrate through the inner shell to be communicated with the boiler chamber. According to the multifunctional, efficient, energy-saving and environment-friendly boiler for both heating and steaming, the defect that the bottom of a traditional water tank cannot be directly heated is overcome, water is rapidly heated, and efficiency is higher; due to the fact that flame energy is recycled, losses are reduced, and energy is saved.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving boiler, in particular to a multifunctional, high-efficiency, energy-saving, environment-friendly, heating and steam dual-purpose boiler. Background technique [0002] It is well known that there are many types of heating and steam dual-purpose boilers at present. Due to the stove heating boilers of the prior art, when the fuel in the stove is burned, the heat of carbon dioxide gas generated in the stove is discharged into the space along with the vertical chimney, and a large amount of heat is generated. When the heat is discharged into the space with the flue gas, the heat absorbed in the storage water of the heating boiler is reduced. This is a difficult problem for the heat absorption in the storage water of the stove heating boiler. life concept. [0003] In today's low-carbon society, more and more people understand energy saving and consumption reduction. The widely used energy-saving...

Problems solved by technology

Its disadvantages are: 1) The chimney is set on the upper part of the furnace body. During the combustion of the coal, most of the heat is heated on the chimney, and only a small part of the heat is absorbed, resulting in a large energy loss.

2) The high-temperature flue gas is directly discharged from the spiral pipe. The high-temperature flue gas stays in the pipe for a short time, and the heat cannot be fully absorbed by the pipe and water, and a large amount of heat is discharged with the high-temperature gas.

However, large particles are not easy to be carried out by high-temperature flue gas, and they will also block the duct; if the air blowing volume of the fan is small, large particles and dust are easy to stay in the pipe due to their own gravity. inconvenient
