WNS What are the advantages of gas condensing boiler with the country's commitment to increasing air pollution control throughout the country have introduced corresponding policy, enacted almost everywhere timing and amount of boiler. In order to save operating costs, most enterprises in the transformation process of the boiler will choose a coal-fired boiler is a condensing gas boiler. So, we need to WNS What are the advantages of a gas condensing boiler detailed understanding. WNS gas condensing boilers What are the advantages of air pollution coefficient small traditional coal-fired boiler during operation will generate a lot of smoke pollution, which is extremely detrimental to the environment, but high-quality gas condensing boiler has to gas as a power source, replacing the traditional coal-fired way. Therefore, there is no coal pollution during operation, which is not only important for environmental protection, but also can reduce harmful gas emission purification device configuration, thus reducing operating costs. Higher safety coefficient due to condensation gas boiler advanced structural design and build these boiler systems have a variety of protective functions of protection, the system comprising high and low voltage protection against dry protection, overheating protection and to prevent leakage protection boiler, by function, the process of condensing gas boiler operation can effectively reduce the potential security risks because of negligence. Small high high-efficiency heat loss condensing gas boiler generated steam can be recovered, not only better water recycling, waste heat can be effectively collected. Meanwhile, the condensing gas boiler advanced temperature control, the internal heat loss of the entire boiler system small, more efficient energy utilization. Therefore, it is possible for enterprises to save a lot of electricity, water and fuel.

Run chemical plant boiler problems that may arise is what chemical plant boiler operation possible problem is? There are two main chemical plant boiler evaporation: evaporation and rated maximum continuous evaporation. When the chemical plant boiler load is higher than the maximum continuous evaporation, it indicates the operating force or overload. The following problems may occur super-load operation: Main results are as follows: (1) due to increased fuel consumption, furnace volume heat load increases, the furnace temperature and furnace flue gas outlet temperature, resulting in the superheater and reheater the superheated steam temperature and wall temperature, and must therefore be strictly monitored and adjusted. Try not to let this time overheating. Coal furnace, furnace volume due to the increased thermal load, increasing the likelihood of slagging. (2) the flow rate of chemical evaporation apparatus system working fluid increases, the flow resistance is increased, it is not conducive to water circulation. Therefore, we should pay particular attention to the monitoring of the water cycle bad area. (3) the pressure differential between the drum and the superheater outlet flow increases as the working fluid and superheater flow resistance increases, so that the pressure of the steam drum and headers increases, the strength of these components must be considered . Space volume load (4) the steam drum, the load increases the evaporation surface, saturated with water vapor would increase, thus affecting the quality of steam. (5) chemical plant boiler safety valve Total displacement designed according to a maximum continuous evaporation. If the chemical plant boiler overload, once the sudden load shedding, the safety valve will not fully open, the steam pressure can not be reduced quickly. At this point, it is necessary to ensure the safety of the boiler by chemical vapor released into the air exhaust valve. (6) With the increase of the amount of air required for combustion and the amount of smoke produced, once sufficient air supply, the air volume is insufficient, the chemical conditions affecting the combustion boiler, increasing the likelihood of slagging; In addition, since the flue gas velocity the increase in fly ash increased the degree of wear of the heating surface. (7) during operation, the exhaust gas temperature rises, the exhaust gas heat loss; shorter residence time in the furnace the fuel, incomplete combustion heat loss of mechanical and chemical incomplete combustion to increase the heat loss, reduce the thermal efficiency of the chemical plant boilers. In summary, the excess chemical plant boiler operation have an adverse impact on the security and economic, should generally not excessive run. If the special emergency must also be strictly limited scope and excess power beyond the time required to force.

The coal fired steam boiler consists of two large boiler drum out of factory , up major possession including boiler body , upper steel frame and furnace wall ,lower bulk including coal bucket ,chain grate ,lower furnace wall, and internal ventilation tube. Fuel: Bituminous Coal, dry-burning coal, hard coal, ligneous coal, etc.

1.Combustion and both sides of the furnace chamber adopt membrane water-cooling wall structure. With this kind of structure, the boiler has a high heat transmission coefficient, low heat loss, good air tightness, no distortion for furnace wall and no ash leakage.

2.Furnace front and rear water wall tube extend down to the upper portion of the grate and form the front and back arch, which extends the span of arch.

3. Inverted “α” arch furnace technology makes the front arch high and short, rear arch low and long. This structure increases the burning time of the flue gas in the furnace so as to improve the combustion efficiency. Besides, the streamline shape of back arch can throw the left carbon grains from the back furnace grate into the front so that the coal is easier to get ignited. Finally, many types of coal can be applied in the boiler.

4.The length of the front and back shaft is longer than the other domestic ones, which prolongs the time of fuel combustion in the furnace and lower the carbon content in the furnace slag. Thus, the overload ability of the boiler is strengthened with the increased effect area of furnace grate.

At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.
