Abstract
The utility model discloses an angle pipe type coal powder boiler with overhead combustors and belongs to the field of boilers. The angle pipe type coal powder boiler solves the problem that an industrial coal powder boiler is small in capacity and not stable in combustion in the prior art. The angle pipe type coal powder boiler comprises at least two combustors, a steam-water system and an air preheating device. The steam-water system comprises a boiler cylinder, a flag type convection bank, an upper collecting box, a converging box, a lower collecting box and a vertical film type water cooling wall. The upper water collecting box and the converging box are arranged on the top of the film type water cooling wall. The lower collecting box is arranged at the bottom of the vertical film type water cooling wall. Downcomers are arranged between the boiler cylinder and the lower collecting box and between the upper collecting box and the lower collecting box. The flag type convection bank is arranged in the convection smoke pipe. The angle pipe type coal powder boiler is mainly applied to industrial coal powder boilers.
Description
Technical field
The utility model belongs to boiler industry, specifically, relates in particular to a kind of corner tube type pulverized-coal fired boiler of overhead burner.
Background technology
Along with the develop rapidly of China's economy, energy-conserving and environment-protective require increasingly strict, and high effect cleaning combustion industry pulverized-coal fired boiler technology is having unique advantage aspect the saving energy and environmental protection.
In recent years, China made a breakthrough at the industrial coal powder boiler applied technical field.The researcher has developed the industrial coal powder boiler technology of multiple pattern, as boiler shell type pulverized coal boiler, the preposition vertical pulverized-coal fired boiler of fast-assembling D moulded coal powder boiler and burner etc., and is applied in engineering practice.Yet, due to the adaptive restriction of boiler manufacturing technology, traffic condition and coal burner, there are many limitation in existing coal dust technology, as less than normal as capacity, combustion apparatus bad adaptability, the problem that operation stability is bad and operating cost is high.Particularly, along with the requirement of social energy conservation and environmental protection is more and more higher, the development prospect of industrial coal powder boiler is good, and large capacity and pulverized-coal fired boiler Stable Combustion Technology more become the emphasis of industrial coal powder boiler technological break-through.
The utility model content
In order to solve the problem of the less than normal and combustion instability of industrial coal powder boiler capacity in prior art, the utility model provides a kind of corner tube type pulverized-coal fired boiler of overhead burner.
The utility model is achieved through the following technical solutions:
The corner tube type pulverized-coal fired boiler of overhead burner, comprise at least one burner, boiler circuit and air preheater, described boiler circuit comprises drum, the convection bank of flag formula, upper collecting chamber, header, lower header and vertical fin panel casing, between described drum and lower header, between upper collecting chamber and lower header, be provided with down-comer, described burner is arranged on the top of burner hearth.
Compared with prior art, the beneficial effects of the utility model are:
The utility model combustion powder burner can be singly only, also can many be arranged on roof of the furnace, and size of burner hearth can carry out design modifying according to the characteristic of burner simultaneously.The present invention has compact overall structure, and burner hearth is good to the adaptability of burning, and flameholding can realize that the breakthrough of large capacity coal dust boiler technology and steel consume the advantages such as low, that safe water circulation is reliable.
