Boiler manufacturer

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 condensing boilers manufacturers in europe 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.

Understand the pros and cons and balance calculations show the efficiency of the condensing boilers manufacturers in europe: boiler efficiency for this important indicator of whether it can have a specific classification? And, in this regard, we should know what specific? These are relevant questions about the boiler, but also related to the important part, therefore, in the next years, will this particular, to explain their work so that we can to gain insight by studying for. Boiler efficiency, which specifically, it refers to a unit of time, the effective use of heat boiler and its ratio between the heat input, or can be said that the fuel units corresponding to the percentage of the heat input in the heat effectively occupied. And, it is an important technical and economic indicators of the boiler, reflecting the operating efficiency of the device, as well as its management level. So, it is a very important parameter. Boiler efficiency, it is also a specific classification, mainly positive balance efficiency and counter-balance the efficiency of both. So below to briefly explain these two specific.

Then, using a gas-fired condensing boilers manufacturers in europe, give users what good is it?

First, clean environment

Combustion air staging the first stage fuel rich combustion, excess air is added in the second stage, the lean burn combustion, the air is cooled between the two was added to ensure that the combustion temperature will not be too high. Combustion air staging and fuel staging combustion contrary, with the first stage fuel lean combustion, fuel is added in the second stage so that the equivalent ratio required value is achieved. These two methods will eventually cause the excess air ratio of the entire system to maintain a constant, low nitrogen currently widely used as combustion control technique. (2) lean premixed combustion technology refers premixed combustion fuel and oxidant completely mixed at the molecular level before the mixture is ignited. For controlling the generation of NOx, this technique has the advantage of controlling the combustion temperature can be achieved by fully controlling the equivalent ratio, thereby reducing thermal NOx formation rates, in some cases, partially premixed and the premixed combustion than non-premixed 85% -90% of combustion to reduce NOx production. Further, the premix can also be reduced completely to reduce the excess air ratio due to unevenness caused by generation control of NOx. However, premixed combustion technology there are still unresolved technical difficulties on the security control: First, because of its highly combustible premixed gas may cause tempering; the second is too high excess air ratio will lead to an increase in exhaust losses , reduces the thermal efficiency of the condensing boilers manufacturers in europe. (3) internal and external flue gas recirculation to reduce the combustion temperature of flue gas recirculation techniques may be implemented by adding a flame zone in the flue gas, the flue gas is added to reduce the combustion temperature of the endothermic.
