450 degree celsius super heater steam boiler

At present, small coal-fired boilers are gradually replaced by clean energy boilers such as gas boilers and biomass-formed fuel boilers, and the operating efficiency of gas-fired boilers is higher because gas-fired boilers burn quickly, generating large amounts of power then coal-fired boilers. It is 20% more efficient and emits less pollutants, which is more beneficial to maintain the environment. Improving the thermal efficiency of gas boilers and making gas boilers more economical is the goal pursued by the boiler industry. The following are several ways to improve the thermal efficiency of gas boilers:

1. The design of the boiler should be reasonable, and the unreasonable boiler structure will cause waste of heat or allow the heat to be consumed in the middle of the cycle.

2. The pipeline connection of the boiler should be checked frequently. If there is any leak, stop the furnace immediately to prevent the occurrence of air leakage.

3. The gas boiler can also play a role in heat recovery, collecting the recycled hot water and reusing it, which is a method to improve the combustion efficiency of the boiler.

How to deal with hot water boiler convection tube bundle fouling conditions: hot water boiler in the long run constantly fouling situation inevitably occur. When the scale accumulated to a certain amount, the need for timely treatment, or will cause damage burst pipes or other parts, causing serious irreversible effects to the boiler. The general approach is the use of other acid or alkaline chemical treatment by immersion or cleaning cycle, it may be used both in combination, but the need for intractable scale more particular method.

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

How full boiler water treatment? 1, the boiler is full of water refers to: (1) the water level is not visible or not, a high level alarm; (2) steam temperature decreases, main steam isolation valves and the turbine inlet valves visible white steam; (3) turbine or steam pipe occurs water hammer; (4) water flow is not larger than the normal steam flow. 2, causes: (1) water supply is automatically jump manually, resulting in abnormal increase of water supply; (2) safety valve on the drum or steam header, resulting in up water or with water; 3) evaporation boiler more overload occurred priming. 3, processing method: a boiler steam pressure and when a normal pressure, the drum water level rises, exceeds + 50mm, the following measures should be taken: (1) the flushing drum were compared with two level table to check instructions are correct. (2) from the automatic to manual adjustment of water supply, water supply and close the door manually turned down and to reduce the total water supply amount adjusting gate. If after treatment b above, within the drum water level is still rising, exceeds + 75mm, should be carried out the following measures: (1) to open the door for emergency drain drum should be put to the normal water level water level shut down immediately. (2) The steam temperature, the heated reducing or closing off the small door, door open and main steam superheater tubes hydrophobic hydrophobic gate. When the treated drum water level continues to rise, and exceeded the upper drum water level meter water level visible, on emergency shutdown, as soon as possible with the main pipe splitting, immediately stop the water, recycled to open doors, turn on the water to strengthen the boiler and steam drum note an upper level of the water table appears to be put to the normal water level off. Standby furnace often the case, the value of the long obtaining consent, according to Stoke furnace operation. C If the drum can not see when the water level within the water table, not in time, should take the following measures: (1) were compared with two wash drum water level table, check the instructions are correct. Full drum water level tables turn on the water door, turn on the water and then slowly close its doors, as there is water in the water table appears, and water levels continue to rise full of tables full of water and has not been proven boiler water level gauge steam over the side of the tube, press the emergency shutdown process. (2) open the door turn on the water table level, and slow to close its doors after the turn on the water, the water level in the water table invisible. To prove a serious full of water, soda and then close the door, turn on the water to open the door, the water level of the water table memory after the release to do, turn on the water shut the door immediately. Ajar quickly and valve inner water table level occurs, and filled with water, before this time has exceeded the determination level of the steam drum level side through the tube sheet, emergency shutdown should be treated as soon as possible and the manifold splitting. (3) When the water level in the boiler accident occurs, it is difficult to judge if the water level should be shutdown immediately. After the shutdown called by the water method called water, check the water level in the drum.

Superheated steam - Wikipedia

Continued heat input will then "super" heat the dry saturated steam. This will occur if saturated steam contacts a surface with a higher temperature. Superheated steam and liquid water cannot coexist under thermodynamic equilibrium, as any additional heat simply evaporates more water and the steam will become saturated steam.

When the last of the pound of water has been vaporized to steam, the stove will have added 970 BTUs to that pound of water to furnish the energy to make what we call a pound of steam. A pound of steam is merely a pound of water that has been trans-formed to steam.
