gas boiler Energy Saving Georgia

Sulphur Dioxide removal

Firing high Sulphur coal requires the use of a Flue Gas Desulphurisation (FGD) plant to keep emissions within statutory limits. An FGD is a complicated plant that requires high capital investment and operational cost. In a CFB limestone addition in the furnace converts the SO2 to sulphates during the combustion and circulation which goes out with the ash. A CFB boiler costs less than a PC fired boiler with an FGD.

Since last year, the city of Yinchuan in Ningxia to develop clean energy alternative to coal heating work carried out, in order to adhere to the use of waste heat energy-based heating system, two years, a total removal of 212 coal-fired boiler energy saving georgia units, designed over 20 million square heating area Meter. At present, Yinchuan City, the formation of a waste heat recovery and cogeneration-based, clean energy co-existence of a new pattern of heating, coal heating gradually withdraw from the stage of history.

According to Yinchuan City Housing Construction Bureau feedback, early last year, Yinchuan City, began to promote the implementation of "East of the West to give a" heat of long-distance heating projects, the long-distance transmission projects across the Yellow River, the basic realization of restructuring heat source, heat source interconnection point to ensure the city heating security and stability, environmental protection is of great significance.

At present, "East of the West to give a" central heating heating net charge of the project, the city branch, etc. have been completed, the east, the city water pipe network has been completed and started flushing cycle, is west of the water, water totaled 145,000 cubic meters.

At the same time, Yinchuan City, also build a heat source, thermoelectric Xixia complete the second phase of construction, the new 2 sets of 350,000 kilowatts supercritical coal-fired air-cooled heat generators, which can effectively replace Yinchuan City, 154 small coal-fired boilers, the annual generating capacity 3.85 billion kwh, heating capacity of 16.42 million square meters.

This year Yinchuan new cogeneration district heating area of ​​41 million square meters, the new heating pipe network 86 kilometers, is the largest investment project ever central heating, with the largest of the year.

Four combustion modes of boiler energy saving georgiaBoiler as an energy conversion equipment, plays a very important role in industrial production, can be said to be the core main force of production enterprises. I know the boiler, but it is estimated that most people do not know much about the combustion mode of the boiler. Today, our Fangkuai Boiler will take you to understand the four combustion modes of the boiler. It can be divided into suspended combustion, boiling combustion, layered combustion and gasification combustion. The following is one by one. First, suspension combustion, also known as fire chamber combustion, is a combustion mode in which fuel is injected into the furnace with air in the form of fog, powder or gas. Suspension combustion ignition is rapid, combustion heat The efficiency is high. It is easy to realize automatic operation. The adaptability to load variation is strong. And the adaptability to the fuel is also strong. However, this combustion mode requires a high level of operation, and should not run intermittently. Secondly, boiling combustion is a kind of fluidized boiling combustion of fuel in fluidized bed under the action of appropriate velocity of air. Boiling combustion is suitable for all kinds of coal, especially inferior coal, such as coal gangue. Stone coal, and so on, this combustion mode on the size of coal particles also have certain requirements. The coal mass must be processed and broken into particles with an average diameter less than 10mm during combustion. Delivered by coal-feeding equipment Enter the furnace. Third, layered combustion, also known as fire bed combustion, is a way of burning fuel in a certain thickness on the grate. This combustion mode is only suitable for solid fuels. However, there are certain requirements for particle size (6~50mm). Layered combustion can basically adapt to solid fuel. As long as the mixture of air and fuel layer is good, and there is a certain combustion temperature, the ideal combustion can be achieved. If the air and fuel layer do not mix well, or the local air supply is insufficient, the combustion will be incomplete and the combustion efficiency will be low. This type of combustion is generally used in chain furnaces. IV. Gasification combustion Gasification combustion mainly refers to gasification and direct combustion of coal put into furnace, and this combustion mode is not suitable for coal with low ash content. High-temperature gasification and staged combustion is different from ordinary gasification combustion. Its utilization principle is as follows: under the condition of oxygen, the fuel surface is heated with high-temperature heat source above 800 ℃, so that the fuel can be rapidly pyrolysis and gasification combustion from outside to inside. Part of the high temperature produced by combustion is then gasified at high temperature, and part of the fuel is discharged for work, thus forming a continuous high temperature gasification combustion reaction.

Check the gas boiler energy saving georgia fuel oil boiler before ignition gas development to today, can be described as advanced technology, but in order to safe fuel gas-fired boiler must be assured, fuel gas-fired boiler before ignition still have to check, and I'll tell below we pre-ignition of fuel gas boiler should pay attention to those aspects: first: fuel gas-fired boiler fuel can be gas, fuel oil if it is, will have to check whether normal pump and filter into the oil; if it is a gas, will have to check the gas pressure is normal , should not be too high or too low. Then open the supply valve of the second oil or gas: a gas oil-fired boiler smoke flue valve, it must look is smooth, not clear if there is a security risk must be excluded. Third: to look at fuel gas-fired boiler control cabinet knob is not in the normal position. Fourth: I have a good job cleaning fuel gas-fired boiler. For our own lives and property in the operation of a gas fired boiler think we must strictly abide by its code of practice for safe operation.
