Developments in the heating of industrial buildings cause in Russia today increased interest. Development of production and service, warehousing requires new technologies to efficiently heat the room large volume. In particular, the increased demand of the air space heating, allowing effective and cost-effectively heat the room capacity from 600 to 20 000 m3. As a fuel, such systems can use natural gas, diesel fuel and, most importantly, the waste oil. Use of equipment for waste oil can dramatically reduce heating costs and increase profitability. When The maximum effect can be achieved where there is an opportunity to receive the waste oil for free: the enterprises service center, railway, port and aviation service stations on factories producing machinery, and vegetable oil, in oil and gas industry. Cost-effectiveness of this development for such companies is obvious: You can use refinement as a fuel and do not need to spend money at its disposal German firm Kroll GmbH for more than 30 years, develops and manufactures systems for air heating systems, using as fuel the waste oil.
During this time, has been thoroughly worked out the technology generate heat by burning different kinds of liquid fuel from waste oil, and any viscous flammable industrial liquids, and ending with used vegetable oil from restaurants and points of Fast-food 'fast food'. Currently in stock firm Kroll GmbH present model heaters, waste oil that can heat the premises from 300 to 6000 m3. The youngest in the line model – the heat generators W401L, up to 29 kW specially designed as an easy to use. Combustion of fuel in this model is a special plate – 'the plate' and the heat comes into the room in the form of infrared radiation or the presence of an additional fan – as a stream of warm air. Low-cost, low automation, simplicity and reliability, compact size make these heat generators indispensable for small workshops and service stations, allowing completely solve the problem of heating remzony area up to 900 m3.
Models of higher level (series S, SKE), up to 200 kW, equipped with a supercharged multifuel burner which can burn the flammable liquids any consistency with a viscosity of up to 90 units. by sae Heat in this case is obtained as air heated to a temperature of 60-70 oC. Execution is possible as the heat generator in the form of an inexpensive candy bar, in which the distribution of air is through the blinds in the upper part, and as a member of the ventilation system when the distribution of warm air is in the system of ventilation ducts. In this case, possible to install a large blower fan pressure and work in the ventilation system. This equipment allows us to efficiently heat the room up to 6000 m3, heat several rooms one heat generator, and create air heat curtains. Equipment firm Kroll GmbH can be successfully used also for heating of any production and storage facilities, but is particularly advantageous to use it where there is a significant stock of used oil: a ports, depots, airports, car repair. In addition to equipment for waste oil, the firm Kroll GmbH manufactures mobile and stationary heat generators for liquid fuel and gas capacity from 15 to 700 kW, as well as water heaters and industrial dehumidifiers.
