Advantages of alternative HHO technology for boilers

1. Catalysis characteristic

--Hydrogen is an active catalyst which can be mixed with air to feed in to catalyze and Combust all solid , liquid , gas fuel. It also can speed up the reaction process, promote combustion completely.

2. Energy saving
--HHO gas is generated only using electricity and pure water. The cost of electricity and water can be reduced more than 30% compared with LPG, Propane, and Acetylene fuel.

--Both economical and practical.Energy Saving more than 10-15 % compared with traditional LPG, Propane, and Acetylene fuel.

3. Safety & Easy Operation
--Steady, reliable fuel delivery.Fuel is available immediately after machine is switched on.No need of gas cylinder, which can rupture or explode.
--Multiple safety devices, including overheating and in-sufficient water cut-off switches, will automatically turn off power to ensure the safety of both equipment and user.

4. No pollution & eco-friendly
--The mixed oxygen and hydrogen gas burns completely without creating pollutants, toxic fumes, or public nuisance.

--No harmful hydrocarbons, carbon monoxide, or carbon dioxide.

5. Low Heat Loss
--Use of oxyhydrogen fuel provide a more focused heat source with less heat loss, maintaining a more comfortable, safer, lower fatigue working environment.

The key technology

1. Principle overviewIn the case of not changing any structure of the boiler and the characteristics of the original boiler, through the pipe and the right amount of hydrogen and oxygen gas mixed into the furnace chamber suspended composite combustion. The chain boiler coal combustion and gas hydrogen and oxygen gas catalytic combustion advantages complementary organic combination together. This composite combustion method not only retains the chain furnace load, but also achieves the purpose of convenient load adjustment.

2. Combustion condition

2.1 after hydrogen and oxygen gas enters the furnace chamber for compound catalytic combustion, the temperature of the furnace chamber will increase by 50~100 degrees.

2.2 when the furnace temperature rises, the grate coal feeding speed will be reduced by 10-30%, and the coal seam thickness will be reduced by 10-30% (adjusted according to the actual operation condition of the boiler).

2.3 after composite combustion, the high temperature area moves upward to the heat intensive area, enhancing the heat intensity of the heating surface and improving the heat exchange efficiency; At the same time, a certain amount of water vapor is produced. The larger specific heat capacity of steam can increase the heat capacity of gas in the furnace, reduce the temperature of flue gas, inhibit the formation of NO compound in flue gas, and capture a certain amount of SO₂. It can reduce the pressure of desulfurization and denitrification of flue gas in the rear and extend the service life of boiler and its auxiliary parts.

2.4 in order to ensure sufficient combustion, the burner must have sufficient air supply, that is, a large excess air coefficient is adopted; However, increasing the excess air coefficient will increase the smoke volume and heat loss of smoke exhaust after combustion, affecting the combustion efficiency. In practical engineering applications, under the condition of ensuring complete combustion, lower excess air coefficient is adopted as far as possible, which is generally controlled at 1.2 ~ 1.3. Excess air coefficient of hydrogen-oxygen gas composite fuel burner = 1.01 , which is already better than the ideal level of gas fuel burner and very close to the ideal value of excess air coefficient = 1. The extremely small excess coefficient of air greatly reduces the heating heat loss of excess air in the furnace and greatly reduces the emission of flue gas. Open hydrogen and oxygen gas in critical condition, and when combustion is stable and emission reaches the standard, the oxygen content is reduced from 3% ~ 5% to 0.2 ~ 0.4, which reflects the stable combustion under extremely low excess air coefficient.When the temperature of the furnace rises, good combustion effect can be obtained by cooperating with frequency conversion adjustment of boiler drum, induced draft fan and coal feed. It can ensure combustion and save electricity.

3. Energy conservation

3.1 the rate of grate feeding coal slows down. After coal seam thinning, the combustion time of coal on grate is prolonged, the ventilation coefficient of coal seam increases, and the carbon content of coal cinder is greatly reduced, thus achieving the purpose of energy saving.

3.2 high temperature upward moving aggregation increases the heat intensity, and water vapor increases the heat capacity in the furnace, which plays a decisive role in boiler output.

3.3 after the temperature of the furnace rises, the blast and draft air are reduced to reach the dynamic balance, that is, the cold air enters the furnace less, reducing the heat loss caused by heating the cold air, and reducing the heat taken away by the draft air, so as to achieve the ultimate goal of reducing heat loss and energy saving and efficiency;

3.4 strong adaptability of coal, lignite and other low-calorific value coal can be fully burned.3.5 after hydrogen and oxygen gas is added to the furnace, the furnace temperature will not increase after 3-5 days, and will remain within a certain range. From 7-15 days, the ash scale and glue on the furnace and boiler heating surface will gradually fall off, and the gas production and boiler output will be further improved.

4. Principle of coal saving

The chain boiler combustion process is first preheating, degassing, decomposition, and then combustion, coal combustion generally accompanied by moisture, degassing decomposition process is long, excess air, low temperature, resulting in coal degassing can not be normal combustion emissions in the form of smoke. And hydrogen oxygen gas and air mix, combustion time is short and complete, can make heat all release.
