The paper presents the theory of calculating heat loss through the fences of timber drying chambers. The software for computer modeling of the process of transferring heat energy through the fences of the drying chamber, consisting of various heat-insulating materials, for calculating heat losses during drying of sawn timber is described. The efficiency of the use of modern heat-insulating materials to reduce heat losses during drying of sawn timber has been experimentally confirmed.

The article assesses the state of the heat economy of the Northern region. The purpose of the article is to reveal the reasons for chronic backwardness of the region's industry from the average Russian indicators. To achieve the goal, solved the following problems: the features of heat economy in the North, analyzes the housing development, production and consumption of heat energy, as the sources of heat energy and heat networks, and also reforms in the heat economy of the region, based on which conclusions on assessment of the heat economy of the region. In recent years, there has been a twofold decrease in the rate of renewal of fixed assets of the heat economy against the norm, low rates of introduction of the resource-saving technologies in the heat economy, and in general, in the housing and communal services of the region. The level of marginal balance of supply and demand in the heat energy market is determined. The article is written to correct the decisions of the Federal and regional Executive authorities in terms of ensuring the reliability of heat economy of the Northern region.

Rotary Dryer

Drying is a critical point for the exploitation of biomass for energy production. High moisture content negatively affects the efficiency of power generation in combustion and gasification systems. Different types of dryers are available however; it is known that rotary dryers have low cost of maintenance and consume 15% and 30% less in terms of specific energy. The study analyzed the drying process of woody residues using a new prototype of mobile rotary dryer cocurrent flow. Woodchip of poplar (Populus spp.), black locust (Robinia pseudoacacia L.), and grapevine (Vitis vinifera L.) pruning were dried in a rotary drier. The drying cycle lasted 8 h for poplar, 6 h for black locust, and 6 h for pruning of grapevine. The initial biomass had a moisture content of around 50% for the poplar and around 30% for grapevine and black locust. The study showed that some characteristics of the biomass (e.g., initial moisture content, particle size distribution, bulk density) influence the technical parameters (i.e., airflow temperature, rate, and speed) of the drying process and, hence, the energy demand. At the end of the drying process, 17% of water was removed for poplar wood chips and 31% for grapevine and black locust wood chips. To achieve this, result the three-biomass required 1.61 (poplar), 0.86 (grapevine), and 1.12 MJ kgdry solids−1 (black locust), with an efficiency of thermal drying (η) respectively of 37%, 12%, and 27%. In the future, the results obtained suggest an increase in the efficiency of the thermal insulation of the mobile dryer, and the application of the mobile dryer in a small farm, for the recovery of exhaust gases from thermal power plants.
