Possible directions for using bran in heat-power engineering

Abstract

Abstract. In connection with the necessity of providing of ecofriendlyness of energy the researches sent to the increase of stake of biomass in fuel and energy balance are actual direction of science and technique. The aim of work is put the study of heating engineering properties of bran and research of possibility of briquetting as it applies to the power use in the stratified fire-box devices. Research methods included standard methodologies of ISO and physical experiment. It is shown as a result of research that bran on the warmth of combustion is comparable with brown coals, but has a less ash-content considerably. However shallow factious composition of bran and caking in the process of ashing will result in high operating costs at their incineration in a natural kind. The variant of the power use of bran is considered as the preforms got the thermal pressing, and the optimal temperature of pressing, equal 150°С. On the example of pressing of shell of cedar nuts possibility of the use of bran is shown as connective, is set here.

Research of the opportunity of using bran as a building material

“…1). A sample of bran (weight is 150 g) was poured into a mold and pressed according to recommendations [7] at a pressure of 10-15 MPa and a temperature of 140°C for 10-20 minutes.…”

“…Options are considered for burning bran for energy needs [7,8]. However, the slagging ability, characteristic for vegetable fuels, leads to low combustion efficiency and quick failure of boiler equipment.…”

The Bran and Grain Grinding Level Affect the Tensile Characteristics of Bioplastics Derived from Wholegrain Wheat Flours

“…It accounts for around 15-25% of the total grain weight and generally comes out as a by-product of grain milling, representing the grinding tail. It is normally used as animal feed, However, the progressive decrease in the whole national livestock occurred in the last dozens of years have implied an increase in bran stocks to eliminate, with thermovalorization as a main alternative [8,9].…”

Dynamic heating and ventilation of transformer substation buildings with adjustable resistance to heat transfer in windows

“…As we know, the reserves of fossil fuels such as natural gas, coal and oil are limited and, according to different forecasts, will be exhausted within a few centuries [1,2].…”
