Water Tube Boiler For Heat Recovery

Water Tube Boiler For Heat Recovery

How full water tube boiler for heat recovery 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.

A large number of accidents showed that gas furnace or water tube boiler for heat recovery flue site of an explosion because of the accumulation of the furnace or flue gas and air mixture, or encountered fire caused by high temperature heat source, and the combustible mixture is clearly mixed gas from the air Forming. Therefore, to prevent the core gas boiler explosion is to prevent the boiler is not running (the furnace flameless) gas into the furnace; and to be noted that, when the boiler starts to be "fire and other gas", i.e., the first gas supply reignition forming source .

The maintenance methods of oil-fired water tube boiler for heat recoverys when they are not used for a long time are: dry method and wet method. When the boiler is shut down for more than one month, dry maintenance method shall be adopted. (1) Wet maintenance method: after the boiler is shut down, the water from the furnace shall be discharged, and the method of wet maintenance shall be adopted for a period of less than one month. Thoroughly remove the internal dirt, rinse clean, reinject the treated water to the full, heat the furnace water to 100 ℃, let the gas from the water drain out of the furnace, and then close all valves, and do not use the moisturizing method in cold climates. The boiler is damaged by ice-free boiler water. (2) dry maintenance method: after the boiler stops the furnace, the boiler puts away the boiler water, removes the internal dirt thoroughly, rinses it clean, and dries it in the hearth with slight fire. Dry (pay attention not to fire), then put a 10 / 30 mm diameter lump of quicklime into a tray and place it in a pot tube without contact with metal. The weight of quicklime is calculated in terms of the volume of the drum at 8 kg per cubic metre. Then close all manhole, hand-hole pipe valves, check every three months, replace quicklime if it is broken, and remove quicklime and tray when the boiler is re-in operation.

Since more than six months since the water tube boiler for heat recovery equipment, heating and hot water supply well, our technical staff also view real-time remote monitoring and control through the use of the boiler to the scene, Baiyun Quan Lake hotel management staff related to our technical staff gave very great encouragement and affirmation. --customer feedback
