Description

Method for saving fuel and increasing efficiency by adding water before or during combustion of various fuels TECHNICAL FIELD The present invention relates to a method for saving fuel. In particular, it relates to a method for saving fuel by adding water. The main purpose is to use and master the time, amount and method of adding water.

technical background

Currently, various fuel substances require water for combustion. At the same time, water is an energy source, fuel, and fuel-assisting substance. Water generates hydrogen and oxygen under the high temperature of various combustion appliances and equipment. The actual purchase and use of various fuel materials are relatively expensive and inconvenient for transportation, collection and storage. Therefore, using water to partially replace them is both economical and affordable.

Summary of the Invention

The various fuel substances have lost some water and water molecules or the inherent density of some fuel substances themselves before being applied to various combustion appliances and equipment. Therefore, adding water before combustion can fully improve the disadvantages of various fuel substances that are not conducive to combustion or the combustion ability is not fully exerted due to the loss of water and water molecules or the inherent density is very small. To make the combustion fully reasonable. Because water is partially decomposed to generate hydrogen and oxygen when heated to 800 ~ 900 ° C, when heated to 100 ° C, hydrogen and oxygen are generated in all, and its molecular formula is: 2¾0 = 2¾ + 0 ₂ , where hydrogen is The best fuel substance, oxygen is the best fuel-assisting substance. Therefore, adding water before or during the combustion of various fuel substances will not only exert the due and potential qualities of various fuels, but also make water fuel The material effect is brought into full play, achieving energy-saving effects never before achieved.

It is found in practical application that some fuel substances not only increase the combustion value after adding water, but also save fuel and shorten the time required for combustion.

Explanation of chemical equation:

2H ₂ 0 = 2¾ +0 ₂ , when the water is heated to 1000 ° C, it basically turns into hydrogen and oxygen

Replacement page (Article 26) gas. DETAILED DESCRIPTION First, there are two forms of water addition:

(1) Add water to various fuels; 1. Add to the fuel to be burned; 2. Add to the fuel to be burned.

(2) Add water to burning appliances and equipment: Add water when the temperature in the burning appliances and equipment or the temperature of the flame point of the fuel in the burning appliances and equipment reaches 800 ° C.

Second, the amount of water:

The amount of water added is an indeterminate amount, and this indeterminate amount changes with the comprehensive consideration of various fuel types, fuel quality, external conditions, fuel consumption, types of combustion appliances and equipment, models, specifications, and actual requirements. Generally, the minimum amount of water added is from 1: 0. 0001, and the highest is 0: X (where the ratio is the weight ratio of fuel to water, 0 means no fuel, and X means non-quantitative water)

Third, add water:

There are many ways to add water. Which one is used should be convenient and effective in practical use. Such as: shower type, spray type, faucet type, basin pouring type, etc. Generally, shower type, spray type and faucet type are mostly used. For example: The faucet type can be used for coal-fired chain-type semi-automatic boilers, which is convenient and fast; the shower-type used for coal-fired chain-type full-automatic boilers; and the suspension-type full-automatic large-scale boilers for coal-fired The spray type is used on the top; the spray type must be used on the gas burning appliances; the pot pouring type is generally used on large-area fuel appliances and water is added before combustion.

Fourth, the method of adding water:

Water can be added in one, two, three, or four times. Regardless of the method of adding water, it should be realistic.

For example: One shot method: like diesel with larger burning area. Water is added to the oil at a water ratio of 1: 0.4 or more, which can be added at one time. Like a large coal-fired boiler, once ignited, it can be added at once Water.

The second addition method: There are two stages, one is to add water to the fuel before combustion; the second stage is to add water to the fuel after combustion or directly to the combustion appliances and equipment.

Three-time addition method: In three stages, the first stage is to add water before combustion, the proportion is small, which is good for ignition; the second stage is to add water when the temperature of the combustion equipment and equipment and the temperature of the flame point above 400 ° C after combustion, the proportion It is slightly larger and slower than the first stage. In the third stage, water is added when the temperature in the combustion appliance and equipment and the temperature of the flame point reach 800-1500 ° C, and the proportion is smaller than that in the first stage.

Four-time water addition method: There are four stages. The first stage is to add water before combustion, the proportion is small, which is good for ignition. The second stage is to add water when the temperature of the flame point in the combustion appliance and equipment reaches 400 ~ 800 ° C after combustion. The proportion is larger than the first stage; the third stage is to add water when the temperature of the combustion equipment and equipment or the flame point reaches 800-1000 ° C after combustion, the proportion is slightly smaller than the second stage; the fourth stage is to burn the combustion equipment and equipment after the combustion. Water is added in appliances and equipment or when the temperature of the flame reaches 1000-1500 ° C, the proportion of water added is small.

Example 1: When coal for industrial single-ton semi-automatic coal-fired boilers is dried (when the moisture content is <1% =), water is first added to the coal before the boiler is ignited or started. Water weight ratio) and then sent to the furnace for combustion. After 30 minutes after ignition, after the combustion is normal (or 60 minutes), add water to the coal sent to the boiler, the ratio is about 1: 0.02 (total 1: 0. 0 4, weight ratio of coal to water). After 60 minutes, add water to the coal, the ratio is 1: 1: 0. 02 (about 1: 0.06 in total), etc. After the boiler combustion is normal and stable After another 60 minutes, add water to the coal sent into the boiler, the ratio is about 1: 0.002. Water and coal can be added intermittently, and the coal saving rate is more than 60%.

Example 2: Industrial 10-ton fully automatic boiler

The 10-ton industrial heating or bathing boiler uses the largest coal-saving method because the amount of coal used has reached the rated value.

Only 5 units of this furnace can be used before adding water. After adding water, if it is under perfect management, The quality of the furnace personnel is the best, and the following water adding methods can be used for one furnace.

Water adding method: The coal to be used in the boiler is dry coal (water content <1% = water is added to the place where the coal enters the boiler inlet just before the boiler equipment is ignited or burned, the ratio is about 1: 0. 03, etc., etc.) After 60 to 120 minutes, add water to the coal when the boiler is burning normally, the ratio is about 1: 0. 02 (total 0.05); after 60 to 120 minutes, add water again It is about 1: 0.01, and after 60-120 minutes, the water supply ratio is controlled to about 1: 0.002, so that the coal saving rate in the boiler is about 80%, and the heating and heating rate is about 105%.

Example 3: Burner stove for heating and heating wood

If the wood is dry, add water about 1 hour before it is used for burning to make the water content about 40%.

After the wood is fed into the furnace and burned normally after 40 minutes of ignition, water is added to the wood to be fed into the furnace so that its water content is about 50%. After the temperature in the furnace has increased significantly, add water to the wood in the furnace to make the water content of about 60%. In the end, the wood saving rate reached more than 50%, and the heating and heating rate reached about 110%.

Example 4 _: Civil gas stove

When the gas stove used by residents is lit, when the flame is large, a water spray bottle is used to spray the gas stove at the flame point in a mist form, which can save more than 10-30% of the gas volume.
