    摘要: A method for online monitoring and determining the calorific value of a solid fuel that is currently combusted in a boiler that comprises a combustion chamber (10) with a steam production system, to which the solid fuel is fed from at least one mill (13) connected to a hopper (14), characterised in that the method comprises the following steps: on-line measuring the operational data of the boiler and of at least one mill during the operation of the boiler; collecting the historical data of measurements of the calorific value of the solid fuel and the operational data of the block; calculating the energy balances of the steam production system based on the collected historical data; iteratively determining (207-212) the efficiency of the boiler based on historical data by: determining (208) sets of mill characteristics depending on a calorific value of the solid fuel and operational data of the mill while combusting that solid fuel; determining (210) the fuel mass flux based on the set of mill characteristics (208); determining (211) the actual calorific value of the fuel (LHV) for the historical data; training a model (407) based on artificial intelligence algorithms to predict the calorific value using the historical data of fuel calorific value (211) and measured operational data of the boiler; determining (408) in real time, using the trained model, the calorific value of the solid fuel that is currently combusted.

    摘要: A boiler designed for combusting gas or oil should be fired using dust without requiring modifications to the boiler apart from replacing the devices used for firing the boiler. The coal dust is introduced in a fluidized state into a combustor (8) and is partially combusted therein, whereby the burning air/fuel mixture is accelerated to a flame (11), which has a high velocity and which is blown into the firing chamber (1) of the boiler. At least 30 % of the fuel is combusted inside the combustor (8) under a pressure that is at least 200 Pa greater than the pressure inside the firing chamber (1). The flame (11) is directed into the firing chamber (1) in such a manner as to effect a more rapid circulation of the flue gases therein. This results in compensating for the reduction in the corner temperature by increasing the heat transmission coefficient, and in achieving a complete burn-out of the fuel without modifying the design of the boiler.

    摘要: The burners provide combustion of a particulate fuel and many types of varying moisture content biomass fuels. The burners exhibit a high turndown ratio. They have a housing defining an upright combustion chamber (9) lined with refractory material and generally circular cross section, a main combustion region within an upper extent of the combustion chamber (9), an initial combustion zone at a lower end of the combustion chamber of reduced size cross section (3) compared to the combustion chamber and a transition region (5) increasing in cross section from the initial combustion zone to the main combustion region. A principal fuel is supplied with combustion air to the initial combustion region. Tuyeres (8) controllably introduce combustion air tangentially into regions of the combustion chamber. A preheat tube (13) within the combustible gas heating chamber receives heated exhaust gas from the burner.
