The paper presents the results of experimental studies of energy (calorific value, ignition delay times and threshold ignition temperatures, duration and temperature of combustion) and environmental (CO₂, NO_x and SO_x emission) characteristics of fuel slurries based on pulverized wood (sawdust), agricultural (straw), and household (cardboard) waste. Wastewater from a sewage treatment plant served as a liquid medium for fuels. Petrochemical waste and heavy oil were additives to slurries. The focus is on obtaining the maximum efficiency ratio of slurry fuel, calculated taking into account environmental, cost, energy and fire safety parameters. All slurry fuels were compared with typical coal-water slurry for all the parameters studied. A comparison was also made between slurries and traditional boiler fuels (coal, fuel oil). The relative efficiency indicator for waste-based mixtures was varied in the range of 0.93–10.92. The lowest ignition costs can be expected when burning a mixture based on straw, cardboard and oil additive (ignition temperature is about 330 °C). The volumes of potential energy generated with the active involvement of industrial waste instead of traditional coal and oil combustion are forecasted. It is predicted that with the widespread use of waste-derived slurries, about 43% of coal and oil can be saved.

本文介绍了能源（热值，点火延迟时间和阈值点火温度，燃烧持续时间和燃烧温度）和环境（CO ₂，NO _x和SO _x）的实验研究结果。排放物）的特征是基于木屑（锯末），农业（秸秆）和家庭（纸板）废物的粉状燃料。来自污水处理厂的废水用作燃料的液体介质。石化废料和重油是浆料的添加剂。重点是获得泥浆燃料的最大效率比，该比值要考虑到环境，成本，能源和消防安全参数进行计算。对于所有研究的参数，将所有浆状燃料与典型的煤-水浆进行了比较。还对浆料和传统锅炉燃料（煤，燃料油）进行了比较。废物基混合物的相对效率指标在0.93-10.92之间变化。燃烧基于秸秆的混合物时，可以预期最低的点火成本，纸板和机油添加剂（着火温度约为330°C）。预测了通过积极参与工业废物而不是传统的煤炭和石油燃烧而产生的潜在能源的数量。据预测，随着废料浆的广泛使用，可以节省约43％的煤炭和石油。
