Water-Tube Steam Boiler

After the water returning circuit is simplified, the flow resistance of water is reduced and the flow speed of riser goes up. As to the high flow resistance of water circulation on both sides of water-cool alls, the injection device is added to improve the reliability of the smooth and safe operation of the boiler.Features: 1) Adequate heat absorbing surface can make a full use of the    heat of the fuel through working medium. The smoke emission    temperature is about 160oC2) The temperature of the furnace chamber and the disturbance of    smoke in high heat section are improved, so as to reduce the loss    of heat and flying dust resulted from the incomplete combustion of    fuel3) To make sure the complete combustion of fuel and to improve    smooth operation of the furnace grate and adequate working    surface by using big movable grate pieces4) To increase the heat conducting rate thus resulting in the    increasing of heat efficiency of rearrange the convection tubesThough adopting above measurement, the heat efficiency of all kinds of boilers from 2 to 8MT/h (1.4 to 5.6MW) is 76% to 78%. This heat efficiency is higher than national standard. Combustion air form two sides with respective air chambers and separate control make the working steady and safe. The inertia dust separating device at the outlet make the dust content less than 1,800mg/Nm3, thus meeting the requirements set by the state for this area.These boilers have compact structure. Boilers from 2 to 8MT/h (1.4 to 5.6MW) can be designed packaged type with short installation period and money-saving. The diameter of upper boiler drum is changed from
