three pass tube fire boiler internal construction

Startup three pass tube fire boiler internal construction, steam temperature raised not up how to do? Sometimes the unit startup process will encounter steam pressure and steam temperature has reached the required difference still many problems, especially in such cases tend to occur in front of the turbine Rushes. In this case the following measures can be employed: (1) switch on the discharge portion of the fire-burner nozzle; (2) adjusting the ratio of secondary air, to increase the amount of the lower secondary air; (3) increase the air pressure, air flow rate, the flue gas is increased flow rate; (4) a large bypass opening to the air or exhaust, slightly lower steam pressure, and then cast by fire mouth, improving furnace thermal load.

The reason for the high exhaust gas temperature following points 1, leakage is serious leakage refers to the furnace, flue, etc. due to poor quality welding or other causes leakage phenomenon is an important reason for the high temperature exhaust gas three pass tube fire boiler internal construction. Mainly refers to the furnace roof seal leakage, see the crater, and the bottom seal Manhole leakage at the sink; chimney flue leakage refers to leakage when the ambient air in the negative pressure operating chamber wall and at the flue imprecise, especially in the furnace end leakage greatest impact. Leakage will make the exhaust volume increases, exhaust heat loss will also increase. 2, hot air factor is too large the air ratio has an important influence on the boiler thermal efficiency and combustion conditions. When the air ratio is too large, the amount of the boiler flue gas emissions will increase, so that the boiler flue gas heat loss increases, induced draft fan, blower power consumption will increase, resulting in reduction in thermal efficiency. Choose the right air ratio, it will reduce the energy losses, get a higher thermal efficiency of the boiler, and the safe operation of the boiler. When the load changes, can be adjusted into the furnace fuel and air quantity, the corresponding changes in the combustion conditions. 3, more fuel moisture content on water in fuel combustion is the main cause burning fire difficult, and reduce the temperature of the combustion zone, the fuel may not fully burn. When the fuel water every 5% increase, due to the thermal efficiency of the boiler heat losses will drop about 0.5%. 4, heating surface scaling, fouling, boiler slag when the heating surface due to poor water quality when the water content of the fuel or the like caused by excessive scaling or corrosive conditions, will produce heating surface scaling, fouling, slag and other undesirable phenomena, will effect of heating surface and heat transfer to the flue gas, the flue gas can not be cooled in a timely manner, resulting in exhaust gas temperature.

The difference with other similar electric three pass tube fire boiler internal construction heaters at 1, what are the advantages compared with the radiant heater (little sun)? (1) life better than radiant heaters. Since the radiant heater as an ordinary electric wire electric wire and exposed in the air, thus greatly reducing its service life, can not be compared with the life of our heaters. (2) better than the radiant heater. Radiant heater use will emit visible light at night can affect people's sleep. Our heater does not have this problem. Uneven heating radiant heater, heating only locally, poor comfort. Our natural convection heater, heat evenly and comfortable. (3) secure than radiant heater. Radiant heater exposed electric wire, when used in a humid environment, the risk of leakage easily occurs. Children while playing as a foreign object is inserted into the radiant heater, it is very dangerous. Our heater level of protection is IP24, can be used in bathrooms and other damp environment, security is very high. Wide range (4) applies, appearance can be used in homes, offices, schools, shopping malls, hotels and other places. 2, compared with geothermal cable What are the advantages? (1) The first is the low energy consumption. Geothermal heating cable to put the entire floor, the floor itself to large amounts of heat loss, and also a part of the heat to the ground or downstairs, wasted a lot of power. (2) The second advantage is that the heat faster. Electric heating can be substantially open desired temperature is reached twenty to thirty minutes within a room, and geothermal cable to at least three to four hours using far less flexibility heater. (3) The third is the construction convenient, easy maintenance and low installation costs. Our simple heater installed as long as there is a wall socket and switch can be used, and geothermal cable construction maintenance is extremely complex and expensive.

Cooperation with the fast three pass tube fire boiler internal construction really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
