Combustion boiler with inlet air filtering function

Abstract

The invention discloses a combustion boiler with an inlet air filtering function. The combustion boiler comprises a heating box, wherein the edge part of the outer wall of one side of the heating boxis fixedly provided with a thermal insulating board through bolts, an air inlet is formed in the outer wall of one side of the thermal insulating board, and a fuel gas pipe is welded on the inner wallof one side of the air inlet; the end far from the thermal insulating board of the fuel gas pipe is connected with an air inlet pipe through threads, and a limiting ring is welded on the outer wall of one side of the air inlet pipe; mounting grooves annularly distributed at equal intervals are formed in the outer wall of one side of the air inlet pipe, and connecting blocks are inserted into theinner walls of one sides of the mounting grooves; and filter nets are fixedly arranged on the outer walls of one sides of the connecting blocks through bolts. Mixed fuel gas in the air inlet pipe canbe filtered, and dust in the mixed fuel gas is prevented from entering the combustion boiler, causing a scaling layer and affecting the heating effect of the combustion boiler, so that the use durability and stability of the device are improved, the combustion time and stroke of the fuel gas in the combustion boiler are increased, and the combustion efficiency and the heat transferring rate of thefuel gas are increased.

Description

technical field [0001] The invention relates to the technical field of combustion boilers, in particular to a combustion boiler with an air intake filtering function. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, whi...

Problems solved by technology

[0003] The existing combustion boiler air intake device is easy to enter some dust in the outside air. After a certain period of use, some dust and dirt will accumulate in the combustion boiler, resulting in poor combustion and heating effects. Therefore, there is an urgent need for a combustion boiler with an intake filter function. to solve the above problems
