biomass hot water boiler for 1200 square heating area
To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired boiler inspection pull the plug on a regular basis in October 2018.
Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.
Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.
Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.
Hot water 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 biomass hot water boiler for 1200 square heating area, 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.
Whether the output of hot water, steam or thermal oil, and regardless of using coal, oil, gas, biomass or power boiler, has the following "four", namely boiler waterwall tubes, superheater tubes, reheater tubes and economizer tubes. It covers all four pipes of the boiler heating surface, the internal pressure of the working fluid bear, may be external to bear the high temperature, harsh environment corrosion and wear, excessive reconcile between water and fire, where the energy is concentrated is passed .
How to choose a steam boiler heat exchanger? Steam boiler heat exchangers are generally divided into two categories, one is a direct contact heat exchanger, and the other is an indirect heat exchanger. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass biomass hot water boiler for 1200 square heating area, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. They are used to recover flue gas heat, to achieve energy saving effect of the separation device. In general, conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increased waste heat recovery installation, which is energy-efficient steam boilers advantage. To promote energy saving is largely the cause of the country, to create more profits for the company, cost savings. Choose a good heat exchanger is one way to achieve energy efficiency goals. Direct contact heat exchanger is a steam boiler with heat recovery and a high ability to remove pollutants in flue gas, but acidic water quality, not easy to use in hot water heating boiler. The so-called indirect heat exchanger, thermal energy means that we recovered from the condensed-called flue gas. Today, more and more people choose to use the steam boiler, the proportion of the market is also increasing. Such steam boiler flue gas discharged contains a large amount of steam, by condensation and release large amounts of latent heat of vaporization. Coal-fired boiler efficiency is much higher than coal-fired boilers. This boiler has a good effect on the selection of the indirect heat exchanger.
