gas steam heating boiler for district heating
Hot water steam heating boiler for district heating for users to solve the "coal" urgent at present, energy conservation and building sustainable economic model has become a national priority, but only our coal utilization hovering around 30%, far below the 78 % of the international average. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees Therefore, improving the utilization of coal combustion has become essential. Currently, coal-fired hot water boiler control system to achieve precise control and real-time monitoring. By controlling the water temperature, the fan speed to achieve a controlled, to ensure the stable combustion furnace pressure and coal, which saves coal, but also to ensure safety. Industrial production in the boiler and heating primary energy into secondary energy of important equipment, has been widely used in industrial production and daily life. Coal-fired hot water boiler control scheme is reasonable and convenient way to monitor, steady state operation, the whole process of thoughtful service, users get a good feedback. I believe in the future, coal-fired hot water boiler intelligent control scheme can serve a wider field of industrial production, as well as hotels, schools, hotels, residential heating, bath, hot water and other fields, coal cost savings for users, improve combustion efficiency, ensure the safe operation provide a solid guarantee. Completely solve the problem of long-term accumulation of the user, the water temperature stable. Water temperature set by the ambient temperature, grate speed difference adjustment according to the actual water temperature and the set temperature of the water, i.e. adjusting the amount of coal boiler, to ensure the stability of the water temperature. Outstanding energy saving. Grate speed changes to the feedforward signal, in conjunction with flue gas oxygen content signal or the furnace temperature, blower speed control using the PID algorithm, to ensure full combustion of the coal, to improve the utilization of coal, reduce emissions of harmful substances. Excellent safety performance. To change the fan speed as a feedforward signal, the PID control calculation and induced draft fan speed according to the furnace pressure value, to ensure the stability of the furnace pressure. This paper introduces a control algorithm based on the level of intelligence of the new big jump lag PID. After control of embodiment, given a certain waiting time to observe the effect, and to determine whether further embodiment control, multi-parameter input and multiple output control mode based on performance parameters.
"Fast steam heating boiler for district heating furnace designed larger, flue gas recirculation provides a reliable guarantee of space. In the burner head design of the special role of combustion, high temperature flame at the outlet of the flue gas interference, be it in the furnace again achieve full combustion cycle (inner loop). this design helps fast boiler leading domestic level in boiler technology, ultra-low nitrogen oxide, the recent large-tonnage party fast brand integrated condensing boiler successful signing in Beijing, and successfully help China build the APEC summit venue. "Fang boiler fast technical director, said.
How to choose the heat exchanger is a steam steam heating boiler for district heating Shandong? To steam boiler insulation damaged condition for viewing prior to use, view of the burner, to see whether the normal operation, but also to see to make sure the valve open position is correct, to view the attachment security equipment, instrumentation equipment and devices automatic control equipment must meet the requirements. Point blast furnace steam boiler admit items are: open oil circulation pump before and after the valve, the valve open oil heating process, mediation high tank level in a reasonable position, admitted that the gas pressure before the gas burner must be burned in power scale, power supply normal.
