Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam manufacturer water pipe boiler steam steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
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.
Boiler start-up process, the drum, the lower wall temperature difference is how to generate? During start-up, the drum wall absorbs heat from the working fluid, the temperature gradually increased. Start early, manufacturer water pipe boiler steam water circulation has not been correctly set up, the drum water is not flowing state, convection heat transfer coefficient of the wall of the drum is very small, i.e. very slow heating. An upper drum into contact with saturated steam at elevated process pressure, a portion of the vapor will condense adherent, exothermic condensation of the metal walls of the drum, which convective heat transfer coefficient than the lower aqueous many times higher. When the pressure rises, the upper wall of the drum can be relatively close to the saturation temperature corresponding to the pressure, while the bottom wall is raised very slowly. Thus formed on the drum wall temperature is high, the low temperature condition lower wall. Boiler boost faster, the larger the temperature difference between the lower wall. On the drum, the temperature difference of the lower wall, the upper wall of the drum by the compressive stress, tensile stress by the lower wall. Large temperature difference, the greater the stress, the drum tends to cause severe shape deformation of the extrados. To this end, China's relevant rules of order: the drum, the lower wall allows the temperature difference is 40 ℃, the maximum does not exceed 50 ℃.
Gas-fired manufacturer water pipe boiler steam nameplate, it is a lot of content, including the boiler parameters. Moreover, these are important parameters, which will also be involved in the product specification, so, if you need to know, you can look at these two parts to get the specific values of the parameters.

Mar 28, 2019 · Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.Get A Quote

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.Get A Quote
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.Get A Quote

A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.Get A Quote
