Denmark and Finland have adopted biomass fluidized bed technology and have long developed biomass power generation and biomass coupled power generation in small fluidized bed boilers. ...
FOREWORD ACS supplied a dedusting equipment for boiler manufacturer Dan Power who integrates the equipment in the boiler package, for end customer FS Bioenergia. Dan Power was founded in April 2001 as an engineering company specialized in energy recovery boilers for cogeneration plants using turbines or gas engines, steam equipment for sulfuric ...
This type of boilers is very popular in recent years. Energy saving circulating fluidized bed power plant boiler mainly used for large central heating, thermal power plants to generate electricity or other purposes Type: ZG Capacity/Hot Power:35 ~ 670t/h ZG Pressure: 1.25 ~ 13.7 MPa ZG Temperature: ...
Due to the low total concentrations of heavy metals and extractable compounds, it is recommended that the wet scrubber residue be used as a construction agent instead of being disposed of in landfills. According to five–stage sequential extraction, the highest concentrations of most of the heavy metals occurred in the residual fraction (i.e., HF + HNO3 + HCl), which means that the heavy metals in ...
A techno-economic feasibility study has been conducted to investigate the revamping of two 32 MWe Pulverised-Coal (PC) boilers with a number of firing options. The options investigated were: (1) conventional PC revamping, (2) replacement with a new PC boiler, (3) PC to Circulating Fluidised Bed (CFB) revamping, (4) replacement with a new CFB boiler, and (5) Bubbling Fluidised Bed (BFB) revamping. ...
In the following paper, the special features of catalytic combustion, which are distinct from the developed theory of flame combustion are considered. They are connected with the properties and characteristics of catalysts, the developed surface for reaction and the comparatively low catalysts' temperatures. They determine the rate of catalytic reaction and the corresponding three main regions of ...
The new advantage of catalytic boiler consisting of the location of heat source near the consumer is described. It imposes some restrictions on the design of such a boiler, which is based on the zonal arrangement approach. The details of such design of boilers with catalytic fluidised bed intended for different purposes (water heating, steam generation, steam superheating) are considered and, in ...
In this paper, conditions of work, special features and problems of boilers with catalytic fluidised bed are described. The specific conditions, when the catalyst layer remains stationary and granular or becomes spouting, are also considered. There are some main zones in the catalytic boilers with fluidised bed, which characterise such boilers and which must exist in them under normal working ...
The new method of decreasing NOx emissions in catalytic boilers consisting of two-stage (two-chamber) fuel oxidation is presented in the following paper. The corresponding plant and parameters in it are described. The second part of article contains the comparison of technical and economic characteristics of Russian and foreign hot water catalytic boilers with fluidised bed and fixed ...
