Description

Hot water boiler using coke as fuel {A boiler by using a cokes}

The present invention relates to a hot water boiler using coke as fuel to minimize heat loss.

In detail, the combustion chamber wall is composed of an inner plate, an outer plate, a heat insulating material, and an outer wall, and the lower floor material is made of cast iron to withstand heat and at the same time, the ash falls down after coke combustion, and the combustion material is disposed at the bottom thereof. In order to minimize the speed of the combustion gas flowing out through the heat pipe, the heat exchanger tube is installed horizontally with the ground, and the heat exchanger tube is installed horizontally with the ground. During the passage, the water flows in direct contact with the heat pipe and the outer wall of the communication to increase heat utilization efficiency.The hot water tank is installed on the wall of the combustion chamber as well as the upper part of the combustion chamber, and is connected to the upper hot water tank by the hot water passage to minimize the The residual heat can be used for hot water heating. The present invention relates to a hot water boiler using cocos for fuel.

Looking at the prior art, coke is used in places requiring large capacity and ultra-high temperature such as melting furnaces because of the short burning time with rapid thermal generation during combustion, the combustion characteristics of such coke, that is, mass combustion is required and sudden high temperature Due to the loss of heat due to the generation and rapid combustion, the boiler efficiency is very low,

Therefore, briquettes, wood, coal briquettes, oil, and the like are mainly used as fuels for medium and small boilers. This problem is caused by excessive oil purchase cost, increased treatment cost of briquettes generated after combustion, and excessive maintenance cost such as the difficulty of continuous purchase of wood fuel.

Korean Patent Publication No. 10-1988-009249 No. 1, 2, and 3 bullets are stacked in three stages and three bullets are lowered at the same time, in the well-known briquette boiler in which no. 1 ash is withdrawn and removed from the boiler, Cut the first half at the upper end of the 3rd bullet location of the built-in crucible penetration container, feast the upper half feast, fix it there, and fix the second crucible and open the hatch hole by opening the part that matches the second crucible at the upper front wall of the shell container. The upper and lower parts of the hook ring are attached to each other, and the detachable front crucible is tightly attached to the inner surface of the door and door which is coincided with the hatch hole, and the rotating door is attached to the outer surface. The horizontal tank of the continuously formed 'S' stapling water bath is placed on the top of the crucible inlet, and the vertical dome is installed on the bottom of the horizontal tank. It is a briquette boiler characterized in that through the front and rear through the tube is installed or the connection tube is mounted over the horizontal tank bottom and vertical tank rear,

In Korean Utility Model Publication No. 20-1998-004094, in a conventional oil boiler using oil and gas as fuel, one side of the oil boiler includes a briquette boiler using briquette, lignite, and firewood as fuel. It is installed, the supply pipe and the discharge pipe for supplying and discharging the water to the heat exchanger of the briquette boiler is directly connected to the discharge pipe and the supply pipe on the heat exchanger of the oil boiler, respectively, the cap of the briquette boiler with a heat exchanger The feed pipe and the discharge pipe for supplying and discharging water to the heat exchanger to cover the pipe is a boiler characterized in that the pipes are connected to the supply pipe and the discharge pipe branched,

The above devises are boilers that use oil, gas, briquettes, wood, etc. as main fuels, resulting in excessive fuel purchase costs and excessive post-combustion treatment costs such as briquette materials.

In addition, domestic utility model registration No. 079690 allows inexpensive coke to be used as fuel in medium and small heaters due to its combustion characteristics (such as large combustion, rapid combustion, and ultra high temperature generation of combustion temperature). To this end, it is equipped with a re-collection box with an air opening and closing tool attached to the lower part of the combustion chamber of the heater to extend the combustion time of the coke and to maintain the combustion even in a small amount. The flue gas outlet is equipped with a flow control valve communication device. In order to withstand the extremely high heat generated during combustion, the combustion chamber wall is related to a boiler and a co-heater with a coke made of refractory walls instead of cast iron or cast steel.

This design increases the efficiency of heat recovery to some extent by using a flow control valve communication system, but the heat pipe and communication are vertically connected, which limits the extension of the passage time of the combustion gas. There is a problem that heat loss through the outer wall and the heat recovery rate in the case of a small amount of combustion in the combustion chamber is very low, and the heat loss corresponding to the hot air flow rate is largely used in the upper part of the combustion chamber by using not only a hot water tank but also a hot air fan. There is an inevitable problem.

The present invention to solve the above problems,

Communicate with the heat pipe in order to control the passing amount of combustion heat of the boiler, but install the communication in the 90 ° direction to the heat pipe and horizontally with the ground to apply the residence time of the combustion gas that escapes into the communication through the heat pipe as long as possible. In order to maximize the heat recovery efficiency, the water of the upper hot water tank is configured to flow in direct contact with the communication outer wall as well as the heat pipe, and the lower hot water tank not only in the upper part of the combustion chamber but also around the combustion chamber wall. The application of 360 ° all minimizes the loss of combustion heat through the lower combustion chamber walls and ensures that all of the minimal residual heat in the combustion chamber can be used to heat the hot water, while the lower hot water tank is fueled by coke that connects to the upper hot water tank through the hot water passage. It is about hot water boiler to use by

This has the advantage of speeding up the water temperature rise even when the initial heat of combustion of the boiler is low, and it is possible to minimize the heat loss through the wall of the combustion chamber even during the rapid combustion, and to efficiently heat the inexpensive coke heat. It is intended to be used in a boiler, so that it is possible to quickly increase the temperature of the initial combustion, maximize the thermal efficiency and reduce the fuel cost.

The present invention to solve the above problems,

Combustion chamber wall is composed of inner plate, outer plate, heat insulating material and outer wall, and the lower floor is made of cast iron to resist heat and at the same time the ash falls down after coke combustion, and the ash is collected to process the combustion material at the bottom. The open and close communication, the combustion gas outlet, is installed horizontally with the ground to minimize the speed of the combustion gas exiting the communication through the heat transfer pipe.The heat transfer pipe is placed above the combustion chamber and the water flows through the inlet and outlet. The efficiency of heat is increased by directly contacting the outer wall of the heat pipe and the communication pipe.The hot water tank is installed on the wall of the combustion chamber as well as the upper part of the combustion chamber, and is connected to the upper hot water tank by the hot water passage, so that the minimum residual heat in the combustion chamber is also heated. To minimize heat loss, allowing it to be used for heating Hot water boiler using Kokos as fuel,

Conventionally, coke has been used in places requiring large capacity and ultra high temperature such as melting furnaces because of the short burning time with rapid generation of fire power during combustion, and the combustion characteristics of such coke, that is, mass combustion is required, and rapid high temperature generation and sudden The difficulty of sustaining combustion due to combustion is a difficult problem in small amounts of combustion, and even when applied to medium and small heaters, the thermal efficiency is very low due to fuel characteristics.

Therefore, briquettes, wood, briquettes, and oil are mainly used for fuels of small and medium heaters, which leads to excessive fuel purchase costs, increased processing costs of briquettes generated after combustion, and excessive maintenance costs, such as difficulty in continuously purchasing wooden fuel. As this problem comes up,

The present invention is a hot water boiler that makes it possible to use coke fuel efficiently, which makes fuel purchase cost and post-combustion reprocessing cost very low.

(4) for the initial combustion burner blows the mixed gas of oil and air into the combustion chamber during the initial combustion of the coke, and the coke is injected into the combustion chamber for the fuel inlet (11). The hot water passing through the outside of the heat transfer pipe 18 and the communication 12 flows through the inlet 14 and the discharge port 15, and the communication 12 can be adjusted to have a structure that can be opened and closed by a plate. As a hot water boiler using coke as fuel, the lower hot water tank 3 is also installed on the wall of the combustion chamber 8 so that the low heat at the initial stage of combustion can be efficiently used for heating the hot water. The tub 13 is the upper hot water tank 16 Is connected to a reservoir (7), water enters through the inlet 14 is therefore to flow in direct contact on the outside of the heat transfer tubes 18 and the communication path 12, it is possible to obtain a very high thermal efficiency before.
