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.
6. Operation cost saving
In boiler application industry
hydrogen and oxygen gas are mixed with other fuels for combustion.
The catalytic combustion characteristics of hydrogen and oxygen gas
are utilized to fully burn the fuel in the combustion process, so
that the thermal strength of the combustion chamber can be
effectively improved and the emission of dust, sulfur dioxide,
nitrogen oxides, dioxins and other pollutants can be effectively
reduced. It can save 10%-30% of fuel consumption without secondary
Hydrogen and oxygen gas are blended with other fuels. Using
hydrogen gas in combustion process of catalytic combustion
characteristics, and further help other fuel combustion in
combustion process is not fully, makes the hot strength of the
combustion chamber is effectively improved, and also used the
oxyhydrogen secondary or repeatedly the burning characteristics of
combustion in the combustion process is not yet complete combustion
of carbon monoxide CO, H2 hydrogen, ammonia NH4, such as hydrogen
sulfide HS fully complete combustion. This has played an
immeasurable role in energy conservation, emission reduction and
environmental purification, effectively reducing dust, sulfur
dioxide, nitrogen oxides, dioxins and other pollutants by more than
60%, and effectively reducing the emission of air pollutants from
coal-fired, gas, oil-fired boilers and kilns.
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.
