large gas hot water vacuum boiler for sale

Boiler oxygen equipment startup and shutdown procedures, processes 1, check before starting large hot water vacuum boiler for sale oxygen equipment (1) confirm the vacuum pump to start licensing conditions are met, Steam Turbine Shaft Seal has been put into operation, the shaft seal pressure is normal. (2) the vacuum pump running from the DCS screen, check the vacuum pump inlet, gradually increase the negative pressure, an inlet pneumatic valve opens automatically. (3) Check the pump motor starting current time and the return to normal, bearing vibration, moisture separator and exhaust normal level. (4) Check the plate heat exchanger is working properly, the vacuum pump sealing water inlet temperature is normal. (5) by the same procedure, the other two in turn starts the vacuum pump. (6) When the vacuum unit normal, disabled, according to a vacuum pump for backup. (7) can be put into the system to start the vacuum pump started using function group. 2, the step into the deaerator (1) confirm the deaerator electric door starts exhaust, continuous exhaust bypass valve in an open position. (2) When the condensate system rinse qualified, open the door deaerator drainage wash, rinse deaerator Sheung Shui. (3) eliminates the oxygen water quality standards, the water level dropped -900mm, close deaerator drainage flush door. (4) administration deaerator auxiliary steam heating, to turn on the auxiliary deaerator steam isolation tone front door slowly open auxiliary steam pressure control valve to the deaerator, the deaerator feed water control temperature of not more than 4.26 ℃ / min, Note that during heating deaerator vibration, such as when a large vibration, the heating rate should be slow. (5) heating process deaerator administration, continue to use the deaerator Sheung condensate pump to the normal level. (6) When the temperature reached 100 deaerator deg.] C, the exhaust start off electric gate, the auxiliary steam to the deaerator into the automatic pressure regulating valve, check deaerator temperature of not more than 4.26 ℃ / min, deaerator pressure gradually rose to 0.147MPa. (7) auxiliary steam heating process, the water level should be controlled deaerator, vacuum is not established as the condenser, the overflow inhibited from opening, the electric drainage valve to the condenser. (8) the condensate system startup, if necessary, administered deaerator water level adjustment automatically. (9) when the four pumping pressure reaches 0.147MPa, check oxygen pressure, the water level is normal, open to four extraction electric valve deaerator, the deaerator cut four auxiliary steam for the steam extraction, auxiliary steam to the deaerator pressure regulating valve is closed, the deaerator by the constant pressure operation becomes sliding pressure operation. (10) when the extraction four electric valve check valve has been opened, four extraction check valve to the deaerator before the electric air trap closed. (11) continuously adjusting the electric door exhaust deaerator feed water under oxygen. 3, how the boiler deaerator outage (1) when the load is less than 20% of the rated load, the four drawers deaerator steam heating switching supplemented to maintain constant pressure operation 0.147MPa. (2) When the generator is stopped, as the case may decide whether to stop the deaerator Sheung. (3) If the outage deaerator more than two months, it should be used to protect the nitrogen, cut off all the steam source, water, water tanks exhausted than water, close the drain valve, the isolation comprehensive total nitrogen door open doors and isolation of deaerator nitrogen and maintain a certain pressure.

Several sub large hot water vacuum boiler for sale? 1, according to the boiler use classification into thermal power boilers and heating boilers. Power boiler comprising a power station boilers, marine boilers and boiler locomotive, corresponding to power generation, marine, and locomotive power dynamic. Heating boiler comprising a steam boilers, hot water boilers, hot tube boiler, stove and the heating medium heating furnace, to give a corresponding steam, hot water. Hot air and the heating medium and the like. 2, according to the structure classification boiler body is divided into fire tube boilers and water tube boilers. Fire-tube boiler, including vertical and horizontal boiler boiler, water tube boilers and water tube boilers including horizontal, vertical, water tube boilers. 3, divided by boiler coal-fired boiler, oil-fired boiler and gas boiler and pulverized coal boilers, gas boilers with a dual-fuel type classification. Coal-fired boiler by combustion fired boilers can be divided into layers, and in fluidized bed firing boiler chamber. 4, classified by evaporation boiler capacity is less than 20t / h is called a small boiler, evaporation to 75t / h is referred to as large boilers, evaporation of medium-boiler referred interposed therebetween. 5, according to the boiler pressure below the boiler called classification 2.5MPa low pressure boiler, 6.0MPa or more is called high-pressure boiler, a pressure called medium pressure boiler interposed therebetween. In addition, ultra-high pressure boilers, boiler subcritical and supercritical boilers. 6, according to the form of boiler water circulation boiler classified into natural circulation and forced circulation boiler (boiler including DC). 7. The device classified into the form of package boilers, boiler assembly and bulk boilers. In addition, the form wall boiler, vacuum boilers and boiler modules.

Despite the stable and safe operation of the products, the use of gas-fired steam large hot water vacuum boiler for sales should be very common. But it's not that you can manipulate it at will. This time we will introduce some excerpts that must be noted when using gas-fired steam boilers. First of all, it is very important to carefully examine the gas steam cooker before starting the boiler. The review process is very important. We must review these parts. For example, whether the gas pressure is reasonable, whether the windshield of the flue gas pipe is open, and whether the vacuum pump is pumping water. Normal. Wait. The boiler can be started only when the equipment is in good condition, and each steam can be operated safely Safety of steam boilers. Second, using shutdown during shutdown should be a very strict process. First, the fire should be turned into a small fire, then slowly extinguished and the burner closed. There should be a lot of summaries about the safe use of steam boilers. If you can pay special attention to the use of so many abstracts, I think the use of steam boilers is very safe to avoid improper use of details. When the water level is lower than the specified minimum water level, but can still be seen in the water level observation instrument, the water temperature is judged to be insufficient, and when the water level measurement item does not measure the water level height, the water level is judged to be seriously short of water. The generalizations of this phenomenon will be listed in The results are as follows: (1) the water level of the drum is less than the normal water level; (2) the warning of low water level is made automatically and the signal light is on; (3) the steam temperature of superheated steam is increased; (3) the temperature of superheated steam is increased; (4) the water supply is abnormal, which is lower than the value of steam flow; (5) the temperature of exhaust water vapor is increased.
