damper functions in boiler economiser

Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of ​​38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original damper functions in boiler economiser equipment can not meet this demand, therefore, require additional purchase orphanage hot water boiler. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.

Below pic is ZG 75t CFB damper functions in boiler economiser sale to Indonesia.

Project 75ton CFB is capable of removing over 98% of the sulfur dioxide and still improving the overall economics and environmental performance. It is equipped with a polishing scrubber employed to minimize reagent consumption while firing petcoke containing up to 8.0% sulfur. The relatively low furnace operating temperature of about 900 ºC results in lower nitrogen oxide emissions compared to conventional coal-fired power plants. However, the project includes a new selective non-catalytic reduction system to further reduce emissions of nitrogen oxides.

Fuel gas damper functions in boiler economiser thermal control basic requirements: 1. The main characteristics of the fuel gas boiler main difference between the fuel gas boiler burning coal-fired boiler is to layer different combustion systems, mainly in the nature of the fuel and combustion different ways. Fuel gas boiler combustion system has the following two characteristics: 1) If not properly controlled combustion process, the furnace can form a large number of combustible gas mixture, when mixed gas deflagration, the furnace may cause an explosion, causing heavy casualties and property losses. 2 combustion) of fuel gas boiler combustion space, the combustion speed, load responsive. 2. controlled boiler fuel gas and fuel gas requirements of the boiler combustion system adapted to, the following basic requirements for the fuel gas boiler automatic control system: (1) reliable system configured to prevent fuel gas boiler explosion, the design of the fuel gas boiler when automatic control system must be designed to give priority to the reliability of a system, the detection system may employ protective control system provided separately, if necessary. In the selection of microcomputer control system, it is necessary to adopt a dual configuration instructions manual and the necessary back-up of important parameters such as measures to improve the reliability of the control and protection systems.

Feed Water & Steam Circuit – this section deals with supplying of steam generated from the damper functions in boiler economiser to the turbines and to handle the outgoing steam from the turbine by cooling it to form water in the condenser so that it can be reused in the boiler plus making good any losses due to evaporation etc.
