摘要:隨著可持續(xù)發(fā)展的深入推進(jìn)，能源與環(huán)境問題己經(jīng)成為影響我國社會可持續(xù)發(fā)展的關(guān)鍵問題，而我國主要能源消費(fèi)是煤炭和石油，兩者都是不可再生資源，且燃燒過后，對環(huán)境造成相當(dāng)大的污染。煤炭除了少部分用于居民的生活中，大部分用于火電站發(fā)電。如何實(shí)現(xiàn)火電站鍋爐高效低污染燃燒，是我國可持續(xù)發(fā)展的一個(gè)重要環(huán)節(jié)。 鍋爐燃燒問題，是一個(gè)復(fù)雜的物理化學(xué)反應(yīng)過程。在火力發(fā)電廠的運(yùn)行中，由于燃燒成分、風(fēng)煤比例、電網(wǎng)負(fù)荷等多種實(shí)際因素的影響，所以鍋爐燃燒和機(jī)組運(yùn)行狀態(tài)在不斷的進(jìn)行調(diào)整，在確保鍋爐燃燒的品質(zhì)、產(chǎn)量和安全運(yùn)行的同時(shí)，實(shí)現(xiàn)鍋爐的低能耗運(yùn)行，就必須要對鍋爐的送煤、給水、給風(fēng)等運(yùn)行參數(shù)進(jìn)行實(shí)時(shí)的優(yōu)化調(diào)整和監(jiān)控。 本文圍繞火電站鍋爐的燃燒優(yōu)化展開，主要運(yùn)用了現(xiàn)場總線與DCS控制網(wǎng)絡(luò)、信息網(wǎng)絡(luò)和系統(tǒng)網(wǎng)絡(luò)之間的集成和BP神經(jīng)網(wǎng)絡(luò)進(jìn)行仿真。全文共分為三個(gè)部分：第一部分，對燃燒優(yōu)化的背景及意義的闡述，明確目前火電廠實(shí)施燃燒優(yōu)化系統(tǒng)的必要性和可行性；第二部分，了解燃燒原理及過程，提出火電站鍋爐燃燒優(yōu)化措施；第三部分，對鍋爐燃燒優(yōu)化建模，利用MATLAB進(jìn)行仿真，通過實(shí)時(shí)數(shù)據(jù)檢驗(yàn)?zāi)Ｐ偷木唧w操作能力。 關(guān)鍵詞：燃燒優(yōu)化；BP神經(jīng)網(wǎng)絡(luò)；仿真
ABSTRACT:Advance along with the development of sustainable development, energy and environmental problems have become the key problems affecting the sustainable development of society of our country, and the main energy consumption is coal and oil, both of which are non-renewable resources, and after burning, cause considerable pollution to the environment. Coal in addition to a few used in people's life, most used in thermal power generation. How to realize high-efficient and low pollution coal-fired boiler combustion is an important part of our country's sustainable development. Boiler burning problem, it is a complex physical and chemical reaction process. In operation of coal-fired power plants, the composition of combustion, air coal ratio, grid load, and other practical factors, so the boiler combustion and unit operation state is constantly adjusted, in ensuring the safe operation of the boiler burning quality, output and at the same time, realize the boiler running low energy consumption, it is necessary to send coal for boilers, water supply, to the wind real-time optimization of operation parameters, such as adjusting and monitoring. Revolves around coal-fired boiler combustion optimization, this paper mainly USES the field bus and DCS control networks, information networks and systems integration and BP neural network simulation. Full-text is divided into five parts: the first part, the background and significance of combustion optimization, clear at present, the necessity and feasibility of implementation of combustion optimization system; The second part, the understanding of combustion principle and process of coal-fired boiler combustion optimization measures are put forward; The third part, the boiler combustion optimization modeling, the use of MATLAB simulation, through the concrete operation of real-time data, inspection model. Keywords: Combustion optimization；The BP neural network;The simulation |
