First of all, the choice of boiler, pay attention to the following three aspects: 1.

1. Coal applicable boiler unit design is based on the composition of a representative coal design basis, the choice of boiler must pay attention to adapt to the region's coal. In addition, we must choose a new type of boiler with high thermal efficiency and high degree of automation.

2. Parameter selection Boiler in the rated load of 80% -90% of the general efficiency of the highest, with the decline in load, the efficiency should also decline. General selection of boiler capacity than the actual steam consumption of 10% on the line, such as the choice of parameters is not exactly a series of standards, the choice of a higher grade parameters of the boiler. Boiler auxiliary selection should also refer to the above principles

  The selection of boiler auxiliary equipment should also refer to the above principles, to avoid the "big horse and cart".

3. The number of choices The principle is to consider the normal maintenance of boilers out of the furnace, but also pay attention to the number of boilers in the boiler room is not more than 3-4 sets of boilers.

Second, the boiler should be installed economizer in order to reduce heat loss of exhaust smoke, improve the thermal efficiency of the boiler, set up in the boiler tail flue economizer heating surface, the use of flue gas heat heating boiler feed water, to achieve the purpose of energy saving, after installing the economizer, increase the temperature of the feed water, so that the furnace water and the temperature difference between the feed water to reduce the boiler feed water to reduce the heat effect.

   State regulations: Where <4 tons / hour boiler exhaust temperature is not greater than 250 ℃. ≥ 4 tons / hour boiler exhaust temperature is not greater than 200 ℃. ≥ 10 tons / hour boiler exhaust smoke temperature is not greater than 160 ℃, or should be installed economizer.
