Currently, research boiler flue gas heat recovery is a fashionable topic. Boiler flue gas heat loss is the heat loss from the boiler largest one, the exhaust gas temperature increase of 20 ℃, the boiler would lose about 1% thermal efficiency. Installation of flue gas heat exchanger in the boiler flue gas after the air preheater to reduce heat losses the boiler is the main purpose of this system of the program. 1 installation of flue gas waste heat recovery project conceived paper Zhundong Region 2 × 350 MW Unit Project as an example, the use of flue gas heat recovery unit is a flue gas - water heat exchangers, boiler exhaust tail heat heating soda, related systems as envisaged. 1.1 determine flue gas systems engineering program, taking into account factors that operational safety and operational costs, etc., combined with engineering characteristics determine the flue gas system uses low dust area induced draft fan arrangement. 1.2 flue gas heat recovery heat medium grade determined for 350 MW units, the proposed flue gas heat heating condensate systems, the condensate into the system in order to improve the initial temperature. The main thermodynamic system runs as follows: the unit normal opening process, the flue gas heat exchanger inlet and outlet valves open, the water side of the heat exchanger is a closed loop system, condensate flue gas heat exchanger to absorb the water side of the heat exchanger flue gas heat, heated to a certain temperature into the turbine side of the condensate system and heating continued. Taiwan added to the water system expansion tank and regulator for balancing the water cycle, water from the chemical water treatment room. Scope: family, small hotels, small enterprises, small size, easy placement, easy to move. 1, the product volume is less than 30L, national exemption in the boiler, ie without going through the boiler use permits. Meanwhile, the product has a large steam space, good steam quality. 2, automatic intelligent control technology, no staff on duty. Work flexible and can be set to manual or automatic boiler may need to be set to run automatically according to the time period, a day to set up a number of different working hours, the boiler automatically start sharing each heating group heating group cycloconverter cut, so the contact TIME, the same frequency, increase equipment life. The controller for pressure control, calculation, tracking changes in the load to the pumps, electric heating tube automatically stop, and can also be manually controlled. 3, with a number of complete protection, leakage protection, water protection, ground fault protection, steam overpressure protection, overcurrent protection, power protection, the boiler automatic protection, safe home. 4, the boiler body with boiler plate, vertical furnace, girth welds are welding, and X-ray testing, small boiler furnace, mechanical and electrical integration, easy installation and patching; large boiler furnace and electric control split designed to eliminate the influence of electrical control temperature furnace, ensure the stable operation of electrical controls. 5, compact structure, scientific and rational design and advanced manufacturing process, so that a small boiler space, easy to transport and saves space. No noise, no pollution, high thermal efficiency, boiler insulation material of high quality and efficient insulation, low heat loss and energy saving. Electric heating boiler energy to electrical energy, no noise, no pollution. High quality heating tubes, surface heat load is low, high thermal efficiency. Centrifugal glass wool using advanced multi-layer insulation, imported color plate packaging; packaging cover both ends of living, easy installation and maintenance; electrical components is a core part of the electric steam boilers, purchased electrical components used in this product are awarded "China Famous Brand "," Chinese famous brand "products, the state" 3C Compulsory Certification "products; Advanced Configuration molded high-end products, high-end products to meet safe and secure. WDR product is a horizontal power boiler steam boiler, furnace electrical control cabinet using isolated manner, avoiding the heat aging electrical components affect the life; select ceramic heater electric heating pipe, the surface load is low, long life; a separate small flange connection, easy maintenance; their normal service life of about 20,000 hours, the thermal efficiency of nearly 99 percent, quiet, clean, in line with environmental requirements, does not emit NOx (nitrogen oxides) into the atmosphere; run part of PLC control system, Shipping operating button, Shipping indicator, touch screen panel display in English, the man-machine dialogue, operational authorization, real-time information, automatic page turning. Features 1, the use of advanced electric heating pipe, each heating element centralized beam flange connection, set up independently, has a simple structure, high mechanical strength, safe, reliable, easy to replace, the surface load is low, long service life. 2, boiler start, stop fast, run the load adjustment range, adjust the speed, simple operation. 3, the heating element is automatically adjusted according to the temperature difference between the number of load changes and input group heating pipe and automatically converted into order, not only save energy, but also the running time of each set of heating pipe balance, thereby uniformly heated tube life. 4, the heating element can also be manually input or stop, user-friendly and flexible to adjust boiler heat. 5, the use of advanced computer boiler controller PLC programmable microcomputer control and display working pressure set by the man-machine interface, working hours and other functions, can display device status of operating parameters and fault alarm; with reliable performance, high degree of automation , ease of use.
