boiler sectional view fire tube water tube

A, a, horizontal boiler sectional view fire tube water tube heat transfer characteristics: the level of the exhaust gas stream flows, hot gas flows, in the same section on the exhaust gas temperature is low heights, the actual distribution of temperature field very different design, good heat transfer, the use of heating surface Ineffective. When the change in exhaust gas conditions, an amount of steam production boiler serious decline significantly elevated exhaust gas temperature corresponding to the boiler outlet. Under normal or exhaust gas conditions, the yield of steam production not be achieved. 2, the exhaust gas resistance: To solve the above problems, and only increase the flow rate of the exhaust gas (generally 11 ~ 13m / s), to improve the results of the flow rate of the exhaust gas is to increase the resistance of the exhaust gas boiler (boiler design typically 800 ~ 1000Pa, the actual operation to be achieved in general 1000 ~ 1100Pa), i.e. increased resistance kiln system. 3, leakage: boiler hopper generally lower through hopper length, combined with the furnace wall surface is too long, while too much or too long ash discharge point, so that, especially in the design of the sealing difficulties during installation and operation of the boiler as extension of the furnace and increase the number of start and stop time, since the furnace wall, the hopper, the hopper in conjunction with the furnace wall surface, and gray ash discharge hopper binding surface deformation, leakage will vary with the boiler uptime boiler increases. 4, soda cycle: First, due to increased forced circulation pump, so that power consumption increases boiler body; Second, since the forced circulation pump is operated at a relatively high pressure high temperature, more forced circulation pump wearing parts, maintenance is more difficult; Third If forced circulation pump can not be timely maintenance, will have an impact on the safety of the boiler. 5, steel consumption: under conditions equivalent vertical boiler exhaust gas flow rate, due to the poor heat transfer, steel consumption and exhaust steam at the same conditions is greater than the vertical boiler parameters. After the increase of exhaust gas flow, which is less than the vertical boiler steel consumption. 6, cleaning: boiler heating surfaces is a single vertically disposed pipe, the dust attached to the wall surface of the heat pipe and the falling direction crossing does not occur, so that the surface to ensure easy cleaning effect, but in fact: because of the high flow rate of the exhaust gas boiler, boiler clear down the front portion of the exhaust gas into the rear of the ash easily, boiler structure is unreasonable, the rear easily plugging ash. When using continuous cleaning method, we can solve this problem. 7, area: large area, for the production of cement has often not easy to arrange a boiler or boiler exhaust conduit Importers long kiln system resistance is further increased.

Heating boiler sectional view fire tube water tube superheater and reheater local overheating of the reasons which have? Heating boiler superheater and reheater local overheating of the reasons which have? In general, heat unevenness and water is the main cause unevenness superheater or reheater in thermal deviation. Generally refers to thermal unevenness in the heating surface of the thermal load on the width and height directions uneven distribution, uneven water distribution refers to the mass flow rate of the heating surface unevenness.

The horizontal steam boiler sectional view fire tube water tube is compact in structure, small in size and economical in capital construction, easy to install, connected with valves, water, electricity and piping can be operated. Stable operation, convenient adjustment, unique anti-leakage air design, long time to seal fire.

Beiqi Panther car 6 tons of steam condensing one fuel gas steam boiler sectional view fire tube water tube project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
