1.Auxiliary fuel economizer;
Molecular structure of hydrocarbons by the fuel economizer
processing, change, increase the distance between the molecules,
the increase in the number of small molecular fuel viscosity
decreased, the result of the fuel oil before burning atomization,
refined, to improve greatly, spray into the combustion chamber
internal are fully under the condition of low oxygen combustion,
thus the blast volume of combustion equipment can reduce 15% to
20%, avoid to take away the heat in the flue, flue temperature drop
5 ℃ to 10 ℃.After the fuel of the combustion equipment is processed
by energy saver, it can save oil from 4.87% to 6.10% due to the
improvement of combustion efficiency. Besides, it can be clearly
seen that the flame is bright and dazzling, black smoke disappears,
and the furnace is clear and transparent.Completely remove the
coking phenomenon of the combustion tip and prevent recoking.The
phenomenon of slag accumulation on furnace wall due to insufficient
combustion of fuel can be eliminated, and the effect of
environmental protection and energy saving can be achieved.The
pollution to the air caused by waste gas from combustion equipment
is greatly reduced. The harmful components such as carbon monoxide
(CO), nitrogen oxides (NOx) and hydrocarbon (HC) are greatly
reduced, and the emission of harmful waste gas is reduced by more
than 50%.Meanwhile, the dust content in waste gas can be reduced by
30%-40%.Location: between the pump and the combustion chamber and
nozzle, the environment temperature should not exceed 360 ℃.
2.An energy saving device for a condensing gas boiler is installed
on the upper wall.
The exhaust of gas-fired boiler contains up to 18% steam, which
contains a large amount of latent heat which is not utilized. The
exhaust temperature is high and the obvious heat loss is great.The
burning of natural gas still emits nitrogen oxides, small amounts
of sulfur dioxide and other pollutants.Reduce fuel consumption is
the best way to reduce costs, condensing type gas boiler economizer
can be installed directly in the existing boiler flue, recycling of
the high temperature flue gas energy, reduce fuel consumption,
economic benefit is very obvious, at the same time, the
condensation of water vapor absorption nitrogen oxide in flue gas,
sulphur dioxide and other pollutants, reduce the pollutant
emissions, has the important significance of environmental
3.Tube grid adopts condensing waste heat recovery boiler
Traditional boiler, exhaust smoke temperature is in commonly 160 ~
160 ℃, the flue gas water vapor is still in the overheated state,
it is impossible to condense into liquid water and release latent
heat of vaporization.It is well known that the boiler thermal
efficiency is calculated by the low calorific value of fuel without
considering the latent heat loss of vaporization in the high
calorific value of fuel.Therefore, the thermal efficiency of
traditional boiler can only reach 87% ~ 91%.And condensing waste
heat recovery boiler, it reduce the exhaust temperature to 50 ~ 70
℃, full recovery of sensible heat and water vapor condensation
latent heat of the flue gas, increase the thermal efficiency;The
condensed water can also be recycled.
4.The tail of the boiler adopts heat pipe waste heat recovery
Waste heat is the energy that is not utilized in the energy
utilization equipment under certain economic and technological
conditions, namely the surplus and waste energy.It includes waste
heat of high temperature waste gas, waste heat of cooling medium,
waste water waste heat of waste gas, waste heat of high temperature
products and slag, waste heat of chemical reaction, waste heat of
combustible waste gas liquid and waste waste and pressure of high
pressure fluid.According to the survey, the total waste heat
resources of various industries account for about 17%~67% of their
total fuel consumption, and the recycled waste heat resources are
about 58% of the total waste heat resources.
