Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.

Water tube boiler advantages:

1. The cross section of the water tube boiler tube is smaller than the outside of the tube, so the steam flow rate is greatly increased, and the steam generated on the heated surface can be washed away, which increases the heat absorption rate of the pot water.

2. The diameter of the water tube boiler is small, and the pot water capacity is small. Once an accident occurs, the disaster is lighter.

3. The boiler steam water system is complex, the water circulation is good, the evaporation efficiency is high, and the thermal efficiency is high.

See nominally, adding a premix gas boiler called "premix" combustion technology, the fuel before entering the combustion chamber, with the gas in advance (i.e., air) sufficient mixing and precise adjustment mechanism according to to achieve optimum combustion, improve fuel economy also will be about 10%; and can effectively reduce harmful substance emissions in flue gas emissions.

Reason for the early start to strictly control the boiler speed boost: The boiler starts, steam after the ignition is due to the water wall tube absorbs heat generated. Vapor pressure is due to the increasing amount of steam production is increased, the saturation temperature of the steam drum water with elevated pressure is increased. Since the saturation temperature of steam at a lower pressure to pressure change rate is high, the initial boost pressure rise value is very small, the saturation temperature of the steam will increase a lot. Boiler start early, natural water circulation is not normal, low flow rate of water or a lower drum local stagnation, heat water in contact with the drum wall is exothermic, the heat transfer coefficient thereof is small, so the lower metal drum wall temperature rise small; upper drum due to condensation heat of the steam drum metal wall, so the higher the temperature of the upper metal drum, thereby causing the lower drum wall temperature compete phenomenon. Since the drum greater wall thickness, and is formed in an outer drum wall temperature high-low phenomenon. Thus, excessive steam temperature will increase due to uneven heating drum and a greater temperature difference between the thermal stress, seriously affect the life of the drum. It must be strictly controlled speed boost at the beginning of the boiler starts to control the excessive temperature.
