“…The use of coal in combustion causes CO 2 emissions and must be replaced with the use of biomass fuel. The mixed biomass in the industry comes from wood, plantation, or agricultural waste [1][2][3] and researchers have carried out an analysis of the flue gas produced during the co-combustion of coal and biomass [4]. The burning process of biomass produces CO 2 , which will be absorbed by plants, therefore burning biomass will not increase the CO 2 content in the earth.…”

Fluid catalytic cracking (FCC) is a method of cracking vegetable oils into simpler fractions and green fuel oils. One component of the FCC system is the FCC furnace. The FCC furnace is where the combustion process occurs and provides high heat transfer throughout the FCC system, especially for heating the reactor. The reactor temperature is the catalyst cracking temperature. The cracking temperature of the catalyst depends on the feed oil used in the cracking process, such as crude palm oil at 450‒550 °C or crude bio-oil at 300 °C. The fuel for heating an FCC furnace is usually coal. To reduce coal, we use a mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure. The aim of this study was to analyze the mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure to obtain sufficient furnace temperature to heat the FCC reactor, perform analytical calculations to obtain the volume of flue gas formed from the combustion reaction. We conducted two experiments; the first experiment used a mixture of 1 kg of Goat Manure Biochar (GMBC) with 0.5 kg of Azolla microphylla and the second experiment used a mixture of one kg of GMBC with 0.5 kg of Azolla microphylla plus 300 ml of Goat Manure Bio-oil (GMBO). A fuel mixture of one kilogram GMBC with 0.5 kg Azolla is not effective in combustion because the maximum temperature in the furnace is 177 °C but the fuel mixture of one kg GMBC, 0.5 kg Azolla and 300 ml GMBO has a furnace temperature of 472.75 °C, which can heat the stripper up to 313.25 °C so that cracking can occur in the raw bio-oil. Analysis of combustion results showed an increase in total CO2 volume from experiment one and experiment two of 0.966

“…The calorific value of the fuel or the ash and sulfur content are important here, but the key parameters are: reactivity, shape and size of the fuel, shape stability, mechanical strength, and porosity [12,13,14]. The needs and requirements of the market and fuel consumers, in particular the users of top-combustion boilers, are the following: the desired fuel should be of a uniform size, combustion heat (> 25 MJ/kg), low humidity (< 7%), reduced PM2.5, NOx, SOx, CO, VOC, heavy metals emission, low sinterability, low under-combustion and reduced amount of exhaust gases per GJ of heat energy produced [15,16,17,18]. This goal can be achieved by using additives in the form of sorbents and catalysts in the production process, which can be distributed throughout the entire fuel volume [19,20,21].…”

The article presents the results of laboratory combustion tests of the microbriquette obtained from useless coal (grain class of < 5 mm) generated in the production of “eco-pea” (eko-groszek) coal. The briquettes of 1.5 and 2.5 cm3 were made in a roller press of crushed coal granulation down to 2 mm, mixed with a binder and/or catalytic additives and sorbents, then dried to final moisture of about 7%. The tests were carried out on a specially designed stand enabling to determine the differential curve of the weight loss of samples heated to the ignition temperature and then burnt with laminar airflow by natural chimney draft. Comparative tests were carried out with ecopea coal from the “ZG Sobieski” mine. The results indicate that composite fuels, in the form of microbriquette, ignite faster, burn at a higher temperature and leave less ash when burned than lump coal. The greater reactivity of the briquette concerning the lump coal allows for minimizing the air rate by about 10%, which also reduces the exhaust gas volume by the same amount and the stack losses. It reduces the velocity of dust lifting, which leads to the reduction of their emission.
