Content of emissions can reach 30mg or less low nitrogen gas steam boiler: b, (which is the main reason many customers do not choose) the risk coefficient burner, furnace easily knock premix customers reflect? This scenario is suitable, the content thereof can reach the discharge 30mg or less content of nitrogen oxide emissions can be reached 30mg or less, but he has many shortcomings! 1 t boiler low nitrogen / low nitrogen boiler 2 t / 4 t environmental low nitrogen fuel gas boiler main boiler, steam boiler, gas steam boiler steam boiler a low nitrogen condensing nitrogen oxides hot water boiler, gas steam boiler, vacuum hot water boiler, one condensing gas boiler, gas boiler company Canadian GDP. A low nitrogen gas boiler. Broad actively studying low NOx combustion boiler side. a, less premix combustion engine, only some domestic manufacturers and American manufacturers are doing. But the quality of domestic instability, the United States is expensive.

The difference between the atmospheric pressure hot water boilers, hot water boilers vacuum? Currently, many have adopted residential district heating boilers, hot water boiler performance and therefore plays an increasingly important role in the heating of the residents. The most common on the market are vacuum hot water boiler and boiler pressure hot water boiler. However, many consumers know these two hot water boilers thorough enough, there may be some bias. A, different security present, primarily professional vacuum hot water boiler hot water boiler, a hot water boiler internal negative pressure can achieve the purpose of rapid combustion temperature, while by changing the configuration of a vacuum hot water boiler may be related to atmospheric hot water boiler. Therefore, security is more obvious. However, when using hot water boiler pressure hot water boiler as long as the use of some type of guarantee ventilation, and therefore pressure hot water boiler is particularly safe and reliable. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, a water requires multiple cycles fewer burner heated hot water boiler and the atmosphere of a large container only opened once the burner can achieve a good heating effect can be efficient heating. Hot water boiler circulating water and atmospheric pressure hot water boiler. Thermal efficiency of the furnace is higher than the thermal efficiency of the vacuum hot water boiler. Third, the complexity of the equipment in order to ensure different vacuum, vacuum hot water boiler must be installed infrastructure series a vacuum pump, but the average hot water boiler pressure control device need not be employed to maintain the vacuum. Therefore, no complicated control equipment required personnel to operate more simple, the complexity of the boiler equipment in use also have greater advantages, meet the needs of more consumers.

The use of central heating hot water boiler is the best choice for winter heating in northern China. Shanxi Province is located in Chang Darrow Heating Co., Ltd. mainly provides heating and post-service maintenance of heating equipment, heating clients involved in enterprises and institutions, office buildings, residential housing and a variety of commercial and other entertainment venues. With the wide blue sky covered Battle of the project, China's gradual increase in the proportion of heating for cleaning, heating, Ltd. Dalong Chang respond positively to the call of national policy, high pollution intensity wishing previously used, low thermal efficiency of coal-fired boiler to replace the traditional use hot water boiler clean fuel. After comparing many boiler manufacturers, choosing the optimal selection, determined and professional cooperation parties do fast boiler fuel boiler cleaning equipment. Providing a fast side 35 MW gas tube hot water boiler (SZS35-1.6-Y.Q) according to their actual needs.

Boiler oxygen equipment startup and shutdown procedures, processes 1, check before starting boiler 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.
