electricity natural gas atmospheric boiler for sale

3. Adopt flue gas return body coil design, this DC-type structure, show the traditional electricity natural gas atmospheric boiler for sale does not have security.

4. As a result of coil-type structure and therefore, sufficient heating surface so that it will have a higher thermal efficiency.

5. Heat-conductive of boiler, characterized by significant counter-current heat exchanger, combustion exhaust gas temperature and thermal conductivity of the oil exports of the following temperature at 30C.

Boiler installation of "blast doors," What is the role now on the market most of the electricity natural gas atmospheric boiler for sales to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.

Biomass electricity natural gas atmospheric boiler for sale for paper mill

ZG Boiler have been commissioned by many paper mill in many countries to undertake extensive servicing activities on a high-pressure steam boiler. we have gas fired boiler, biomass fired boiler, coal fired boiler to paper mill.

In recent years, as people's growing awareness of environmental protection, the State also intended to promulgate stringent emission standards for nitrogen oxides. This electricity natural gas atmospheric boiler for sale companies made a mandatory requirement - how to effectively reduce nitrogen oxide content in the boiler flue gas. Therefore, a focus on emissions of nitrogen oxides environmental revolution is quietly boiler industry. But for domestic boilers companies this road is not good to go, because the difficulty of controlling nitrogen oxides and more demanding of the boiler, every 1 mg / cubic meter of emissions control will cause the boiler costs dramatically.
