boiler sectional view fire tube water tube

Solution 1, due to the decrease of the atmospheric pressure, the fuel combustion speed slower burn time becomes longer, the carbon dioxide dissociation rate increases, increasing the chemical incomplete combustion heat loss. Solution to this problem is to appropriately increase the furnace volume, increased fuel residence time in the furnace. 2, no influence of the atmospheric pressure drop pairs exiled heat transfer coefficient of the heating surface, but decreases of Flame cause radiation heat transfer coefficient is reduced, so that the overall heat transfer coefficient is reduced. While reducing the radiation heat transfer coefficient caused by furnace exit gas temperature rise increases the convective heat transfer temperature difference, but to ensure that the exhaust gas temperature rises to a certain extent without excessive levels of convection heating surface area of ​​the boiler sectional view fire tube water tube should be appropriate increase. 3, low-altitude wind pressure effect on the smoke characteristics of a large gas-fired boilers, gas boilers running in the plateau region, the burner selection must be a revision in its air volume and pressure, ensure that the output power and boiler burner output.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler sectional view fire tube water tube and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

Energy saving waste heat recovery boiler sectional view fire tube water tubewhich is certified in accordance with the PED (Pressure Equipment Directive), is available in eight standardized versions. It consists of a highly efficient tubular heat ex-changer. An economizer can be integrated as an option, which increases the efficiency of the heat ex-changer even further. A flue gas bypass can be added if required. If no steam is extracted, the boiler will use this for diversion on the flue gas side. This means that the (cogeneration)CHP unit or other waste heat sources can continue operating without interruption.

Hot water boiler sectional view fire tube water tube as special equipment, of course, the safe operation of the most important. Has a more comprehensive security early warning system is to protect the safe operation of the boiler. 5. services in place

What is difference between water tube boiler and fire tube

May 05, 2017 · A water tube boiler 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. In Fire-tube boilers hot flue gases pass through tubes and water surrounds them.
