Vertical Naturally Circulating Fluidized Bed Boiler For Power Station Or Industry

Introduction of CFB Boiler

The ring fluidized bed boiler USES the most industrialized clean coal combustion technology. Circulating fluidized bed boiler USES fluidized combustion, the main structure includes combustion chamber (including dense phase area and dilute phase area) and circulating furnace (including high temperature gas-solid separator and return material system) two major parts. With bubbling fluidized bed combustion technology is one of the biggest difference between high running speed, strengthened the combustion and desulfurization heterogeneous reaction process, such as boiler capacity can be expanded to power industry can accept large capacity (600 mw or above level), circulating fluidized bed boiler has been very good to solve the basic problem such as thermodynamics, mechanics, materials science and engineering problems such as inflation, wear and overtemperature, become difficult to burning solid fuels (such as coal gangue, shale, municipal waste, sludge and other wastes) energy utilization of advanced technology.

Features of CFB Boiler

(1)Install 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 ℃.
The fuel oil of the combustion equipment is treated by the energy-saving device, which can save 4.87% to 6.10% due to the improved combustion efficiency.
Thoroughly remove coke from the burn tip and prevent recoke.
Remove the accumulation of residuum in the furnace wall due to insufficient combustion of fuel to achieve the effect of environmental protection and energy saving.
The air pollution caused by the exhaust gas from combustion equipment is greatly reduced. The harmful components in the exhaust gas, such as carbon monoxide (CO), nitrogen oxide (NOx) and hydrocarbon (HC), are greatly reduced, and the exhaust gas is reduced by more than 50%.
At the same time, the dust content in the exhaust gas can be reduced by 30-40%.
Installation position: installed between oil pump and combustion chamber or nozzle, the ambient temperature should not exceed 360℃.
(2)Install condensing gas boiler energy-saving
Gas boiler exhaust smoke contains up to 18% steam, it contains a lot of latent heat is not used, smoke exhaust temperature is high, sensible heat loss is large.
The combustion of natural gas still emits nitrogen oxides, a small amount 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 protection.
(3)The use of condensing waste heat recovery boiler technology
In the traditional boiler, the smoke exhaust temperature is generally 160 ~ 250℃, the steam in the flue gas is still in the state of overheating, it is impossible to condense into liquid water and release the latent heat of vaporization.
As we all know, boiler thermal efficiency is calculated by low calorific value of fuel without considering heat loss of latent heat of vaporization in high calorific value of fuel.
Therefore, the thermal efficiency of traditional boilers can only reach 87% ~ 91%.
And condensing waste heat recovery boiler, it reduces the smoke exhaust temperature to 50 ~ 70℃, fully recovered the sensible heat in flue gas and water vapor condensation latent heat, improve the thermal efficiency;
Condensed water can also be recycled.
(4)The tail of the boiler adopts heat pipe waste heat recovery technology
Waste heat is the energy that has not been used in energy utilization equipment under certain economic and technological conditions, that is, redundant and waste energy.
It includes waste heat of high temperature waste gas, waste heat of cooling medium, waste heat of waste gas and waste water, waste heat of high temperature products and slag, waste heat of chemical reaction, waste heat of combustible waste gas and waste water, and residual pressure of high pressure fluid.
According to the survey, the total waste heat resources of various industries account for about 17%~67% of the total fuel consumption, and the recoverable waste heat resources account for about 58% of the total waste heat resources.
