Abstract

PURPOSE:To quicken a rise of a flame at the time of ignition of a pressure spraying pot burner and to reduce a foul odor at the time of ignition, by a method wherein an upper air hole is made larger than a lower air hole as compared with the same, air supply paths of the upper and lower air holes are made to become independent of each other and air is supplied by concentrating the same into a lower air hole of the pot at the time of the ignition. CONSTITUTION:An opening and closing door 12 is in a closed state at the time of ignition, and when a combustion blower 10 is turned, air is supplied by concentrating the same in a lower air hole 1'' of a pot 2. As for an ignition operation, mistlike fuel is injected through a spray nozzle 4 while the combustion blower 10 is being turned and the mistlike fuel is ignited by forming a spark at the tip of a spark plug 8. The ignited mistlike fuel is entered into the pot 2 from a through hole 6, the mistlike fuel whose particles are large in their size are drained by coming into contact with cooled inside wall of the pot 2 and a flame expansion plate 3 and only the mistlike fuel whose particles are small in their size can keep the combustion on.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention speeds up the rise of flame when igniting a pressure spray pot burner and reduces odor when igniting.

This type of pressure spray pot burner is different from a pressure spray burner called a gaff type, which burns by directly injecting atomized solvent into a large combustion chamber.The flame ignited in a mist state is cooled by a flame expansion plate that is bent on the side wall or bottom of the pot. Some of the fuel is burned, making it impossible to continue burning, and the mist of fuel that touches the pot wall or flame expansion plate drains and immediately becomes a substance that cannot be combusted. For this reason, as with ordinary pot-type burners, the pot does not become warm until several minutes have passed after ignition, making it difficult to achieve stable combustion, and during this time a foul odor from incomplete combustion occurs.

The purpose of this invention is to improve the rise of flame when ignited.As shown in the figure, 2 is a pot with a large number of air holes in the side wall 5, and 3 is a side wall of the pot 2. It is a very wide-ranging thing that has been penetrated, and the pot ring 5 is attached to the side wall of the pot below the flame expansion plate 3 and V, and the flame expansion plate 3 is attached to the pot ring 5 through the legs. Installation. Reference numeral 4 denotes a spray nozzle that looks into the pot 2 through a through hole 6 made in the pot 2, and the fuel is pressurized by an electromagnetic pump 7 and supplied into the pot 2 in the form of a mist from the spray nozzle 4'. Ru. A spark plug 8 is located in front of the spray nozzle 4, and ignites the atomized fuel.

1' is an upper air hole drilled in the side wall of the pot 2 on the side of the flame expansion plate 3, 1' is a lower air hole drilled from the center to the lower part of the pot side wall, and the upper air hole 1' is a lower air hole. It is much wider than 1'. Reference numeral 9 denotes a partition plate which separates the air passages A and B of the upper air hole 1' and the lower air hole P, and supplies combustion air concentrated to the pot lower air hole 1' during ignition.

That is, IO is a combustion blower, and it is installed in the air flow path B leading to the lower air hole 1''. 11 is a solenoid, 12 is an opening/closing door that is operated by the solenoid 11, and is installed on the partition plate 9 to blow air. The air flowing through the flow path B is branched and supplied to the air flow path A. Reference numeral 18 is an air release door driven by the solenoid l'l, so that the air supplied from the furnace blower 10 is supplied only to the air flow path B. When the air flows to the air passages A and H, the air release door 13 is opened to release excess air to the outside, and when the air is sent to the air passages A and H, it is closed.

A porous cylinder 15 suspended from the pot ring 5 is a small diameter cylinder installed on the bottom of the bot 2, and serves to spread the flame uniformly when the spray nozzle 4 supplies atomized fuel from the side of the pot 2. ing.

In this invention having the above configuration, the opening/closing door 12 is closed at the time of ignition, and when the combustion blower IO rotates, air is concentrated and supplied to the air hole 1'' at the bottom of the pot 2.The ignition operation is While the combustion blower IO is being rotated, atomized fuel is ejected from the spray nozzle 4, and a spark is formed at the tip of the spark plug 8 to ignite the atomized fuel.The ignited atomized fuel flows from the through hole 6 to the pot 2. If the atomized fuel enters the interior and has large particles, it will come into contact with the cooled inner wall of the pot 2 or the flame expansion plate 3 and drain.
, only fine particles can continue to burn.

By the way, in this design, air is supplied concentratedly to the lower air hole 1' of the pot 2 at the time of ignition, and because the number of air holes 1'' is small, this amount of air is drained and substantially reduced. It matches the amount of combustion well, and the flame is not blown out by a large amount of air, and when ignited, combustion occurs with a blue flame that seems to envelop the flame expansion plate 3, which has expanded greatly due to the limited amount of air. It became so.

Therefore, the loudspeaker 3 installed in the pot 2, other pot rings 5, etc., as well as the inside of the pot 2 become hot in a short period of time, and the fuel that drains at the initial stage of ignition gradually vaporizes and the amount of combustion increases. It's coming. Then, after a certain period of time after the ignition operation, or after detecting a temperature rise in pot 2, solenoid 11
'(i: When the switching door 12 is opened, combustion air is also introduced into the air flow path A, and a large amount of air is introduced into the gas being melted from the upper air hole 1' of the pot 2. This enabled the combustion to proceed normally.

As described above, this invention performs combustion without blowing out the combustion flame with a large amount of air, and because the pot is efficiently heated, normal combustion can occur in a short time after ignition, and incomplete combustion occurs. To provide an excellent pressure spray pot burner that generates less gas and less bad odor.
