3 pass fir tube steam boiler

Such as hotel Home Hotel Group is one of the three major brands, in 300 cities in the country has nearly 2,000 hotels. Home Inns has won China Golden Pillow Award for Best Chinese economy hotel chain brand award, in 2014, Home Inns brand value of $ 420 million of selected China's top 100 brands. April 4, 2016, BTG hotel groups such as the privatization of the hotel purchase transaction has been completed delivery. In mid-2016, as a Beijing hotel with our preliminary communication, the urgent need two boilers work of heating and hot water supply. I related technical engineers and recommend it to calculate the number and size of the boiler on the hotel room as hotel Willy sharp V6-99 two models.

Why boiler operation will cause steam temperature change (1) the impact of the steam temperature of the boiler combustion. Furnace combustion conditions change, change directly affects the heating surface of each heat sink share. Administration as discharge changes burner stops, and the nature of the fuel quality, the size of excess air coefficient, and change with the wind mode of the center of the flame, are increased or decreased on the steam temperature has a great influence. Effect of steam temperature (2) of load change. Superheater, reheater thermal characteristics determines the size of the impact load to the steam temperature change, joint superheater currently widely used, the use of convection and radiant superheater two different thermodynamic characteristics, so that steam temperature by Effect of boiler load change is small, but still generally close convection properties, the boiler load increases as the steam temperature is reduced correspondingly raised, lowered. Impact on the steam temperature (3) steam pressure changes. The higher the vapor pressure corresponding saturation temperature higher; conversely, the lower. Thus, as a result of a disturbance of the steam pressure has a more substantial increase or decrease, the steam temperature will be correspondingly increased or decreased. (4) water temperature and desuperheating steam temperature influence on the amount of water. In drum boiler, the feed water temperature is lowered or raised, anti steam temperature can be raised or lowered. Size desuperheating water flow more directly influence the steam temperature drop, lift. (5) Effect of temperature on the high-pressure cylinder exhaust steam of the reheat steam temperature. Reheater and export steam temperature is as high pressure cylinder exhaust steam correspondingly increases the temperature of the lift, it decreased.

Rear of the boiler deposition of combustible material, re-ignition combustion phenomenon known as secondary combustion. The occurrence of secondary combustion boiler, will economizer, Fan burned, when severe may also totally destroyed the rear of the boiler.

Boiler water circulation 1. theoretical value in the form of warm district heating system, a large flow of a low-temperature radiation heating, heating boiler circulating water than conventional radiator heating system should be large, according to cell location and distribution of building floor height parameter, district heating pattern taken by the secondary heat exchanger system, to meet the overall cell mass and the heating effect. 2. The heating system of resistance along the pressure loss, the pressure loss of local resistance and other factors, and equipment to pipelines and fittings specification data calculating determined. When considering circulating pump selection. 3. In the secondary heat exchanger unit circulating pump selection should consider the flow rate, the pipe system resistance and lift the design parameters.
