Industrial High Volume Low Pressure Double Suction Water Pump

In order to make full use of local resources, improve enterprise efficiency, February 28, 2009, Sinkiang Hengfeng ZG Company commissioned Sugar Co. for one of the first industrial high volume low pressure double suction water pump to be able to use local mixed coal-fired circulating fluidized bed boiler. Due to exceptionally dry local climate, local mixed coal moisture is very low, superheated steam temperature is abnormal over-temperature, and many other problems boiler trial run, but after taking the right measures to run properly. 2009, 2010 crop, the total coal consumption 30,000 tons by the transformation of the former boiler down to 2. 20,000 tons. Given the successful transformation of the company in 2010 we put another one Stoker has been transformed, we have achieved good economic and social benefits.

The method of starting the industrial high volume low pressure double suction water pump during boiler startup control drum wall temperature difference of the process to be controlled in a predetermined drum wall temperature difference may take the following measures within 40 ℃: (1) water temperature before ignition can not be too high, not too fast speed, according to rules of execution. (2) water is completed, the bottom may be put into steam heating conditions. (3) strictly control the raising rate, in particular 0 ~ 0.981MPa boosting speed stage should be less than 0.014MPa / min. Rate of temperature rise not greater than 1.5 ~ 2 ℃ / min. (4) should be regularly switching angle oil gun, until the next row when four full cast oil gun, each part as far as possible evenly heated. (5) via the above-described operation can not effectively control the drum, the lower wall temperature, then when the approach or reach 40 ℃ booster should be suspended, and the sewage regularly, in order to enhance the circulating water, and stabilized until the temperature difference is less than 40 ℃ line boost.

Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of ​​38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original industrial high volume low pressure double suction water pump equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.

Henan condensing gas industrial high volume low pressure double suction water pump introduces the working principle and Henan condensing gas boiler, by definition is condensing gas boiler, condensing gas boiler Henan now can be divided into domestic gas condensing boiler and condensing gas boilers commercial product is the difference between the condensing boilers and floor standing condensing wall-mounted boiler two series. Henan condensing gas boiler in which the most important is to realize the nature of condensing technology. The key lies in Henan condensing gas boiler condensing technology, is a new energy-saving, environmentally friendly technology; its principles are not complicated, a simple generalization is the flue gas heat recovery through flue gas condensation. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, so that water produced during combustion of the fuel (e.g. natural gas: CH4 + 2O2 → CO2 + 2H2O) is in a state of steam superheater in the flue gas, with the smoke. the loss of gas from the chimney. Traditional boiler thermal efficiency is generally only 85% to 91%. The Henan condensing gas boiler, that the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor, a substantial increase in the thermal efficiency. Henan works condensing gas boiler: Popular speaking, the working principle of condensing gas boiler is some means for boiler combustion flue gas heat discharged (usually around 140 deg.] C) for recovery of energy through the discharge after the recovery tobacco temperature is only about 60 ℃, so improving the thermal efficiency of about 10%, naturally saved about 10 percent gas, while the energy recovery process, it is also possible to reduce harmful emissions, reduce environmental pollution.
