The water circulation of the double horizontal tube water tube boiler is divided into two parts: one part is the water circulation of the convection tube bundle between the upper and lower horizontal pots; the other part is the water circulation by the water wall tube around the furnace, wherein the water in the front and rear water wall tubes The steam-water mixture directly enters the upper drum, and the steam-water mixture in the water-cooled wall pipes on both sides enters the upper drum through the upper header and the steam guiding tube. The water in each water wall tube is supplied by a down pipe drawn from the lower drum.
Condensing boiler furnace using a technique to improve the thermal efficiency of the boiler of the boiler. Condensation technology is: disposed in the interior of the condensing heat recovery boiler fuel combustion absorbing sensible heat and the latent heat release, mainly the sensible heat of the high temperature flue gas generated in the boiler combustion, heat mainly the latent heat released from the condensation of water vapor. We do not underestimate this part of the heat, compared with ordinary boiler thermal efficiency condensing boilers can be 15% -25% higher.
Condensing gas boiler and process water hammer phenomenon condensing gas boiler 1. The water hammer phenomenon: (1) gave a regular crash condensing gas boiler and in the pipes, sometimes loud sound, accompanied by strong vibration water pipes or steam pipes. (2) gauge pointer swings back and forth, the frequency of sound and vibration consistent. (3) water hammer severe, it may lead to the respective connecting members, such as weld cracking, breakage of the valve. Processing the drum 2. Water hammer: (1) check valve malfunction, combustion should be reduced to reduce the load and pressure boiler feed water shut-off valve closed to stop the water supply, the water supply valve repair quickly. At the same time we should observe the water level to prevent water accidents. (2) means for heating the steam drum when Stokes, should quickly close the steam valve. (3) maintaining the water level in the boiler condensing gas uniformly into the water balance drum. Water hammer is still ongoing, it should be shutdown for maintenance. (4) boiler maintenance, should strengthen water supply, water distribution and water tank repair. 3. The steam treated water hammer pipe: (1) reduced steam supply, close the main steam valve if necessary. (2) Open the trap set on the superheater and steam pipes hydrophobic tank. (3) drum level is too high, the sewage should be appropriate to maintain the normal water level. (4) strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. (5) elimination of water hammer, check the pipe and pipe rack case, flanges, etc., as the case without further heating pipe for a steam supply.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boiler treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
