The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:
1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.
2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;
3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;
4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;
5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;
6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.
7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.

Hot water hot water biomass firewood boiler 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.
