The purpose of this project is: DESIGN, CONSTRUCTION AND ENTRY IN OPERATION OF BOILER, WORKING ON ALTERNATIVE FUEL (SOLID HOUSEHOLD WASTES).
This boiler room allows you to realize the following features: the possibility of using cheap local fuel; solution of the environmental problem of disposal of solid waste in the region; High profitability and reliability in the supply of coolant to housing and public utilities and industrial consumers low installation and operation costs; short payback period of the equipment;
The situation with MSW in Ukraine The population of Ukraine over the past two decades decreased by almost five million people (or 10%) of the number 51 million people in 1990, but the amount of household garbage is not just does not decrease, but, on the contrary, continues to accumulate and increase. For example, over the past ten years the volume of household waste - waste products of each resident in Ukraine increased by 40%. Environmental Safety Department of the Ministry of Protection the environment assesses the concentration in Ukraine of all types of waste in the amount of about 35 billion tons, with 2.6 billion tons being highly toxic. Annually, according to the ministry, the total household waste increases by 50 million cubic meters or 14 million tons (300- 400 kg per year per person), and industrial waste - by 175 million cubic meters.
Problem or Opportunity
Scope of construction boiler room 1. Development of project documentation; 2. Development of the project organization of work (ERP) and the project construction organizations (POS); 3. Implementation of construction works in full; 4. Purchase, manufacture and supply of primary and secondary equipment; 5. Performance of installation works; 6. Implementation of complex commissioning works; 7. Staff training with the issuance of instructions and regime cards; 8. Providing the necessary documentation for registration in government regulatory agencies.
Economic evaluation project efficiency One of the first stages of the project is the development of a feasibility study, thoroughly determining the economic efficiency of the project. The following results of preliminary calculations, however, indicate high expected efficiency and profitability of the project, its high investment attractiveness.
Solution (product or service)
Technical solution An alternative fuel boiler room is planned to be completed at the base utilization furnace-incinerator of pyrolysis type PG-5 and water-heating the boiler. The overall basic design of the boiler remains unchanged. The nominal heat output of the boiler is 3 MW. Scheme of the boiler room: MSW from housing and public utilities come to the sorting line, where they are cut off incombustible fractions (metal, glass, debris), combustible fractions are supplied for preparation and transportation for further automatic burning; The stock of fuel at the rate of operation of the boiler room is always on stock. for 5 days; For ignition and maintenance of the pyrolysis process is used. additional fuel - wood chips, in the ratio of 80% of MSW and 20% chips;

Advantages or differentiators
The heat recovery furnace used in this boiler house operates in the mode pyrolysis, which is achieved by mixing various MSW Sorted with wood chips. Pyrolysis - the most environmental progressive method recycling. The process of gas generation and combustion of syngas takes place in the furnace. that provides disposal of solid waste by thermal destruction at a temperature of 1200 -1300 C, and thus completely neutralizes all toxic constituents. The whole system works under discharging, which excludes the release of products combustion into the work area. Exhaust gases are discharged through the exhaust fan to chimney. Cleaning of flue gases from dust produced in a cyclone. Ash from the furnace is removed from the boiler room with closed augers, installed below the floor of the channels in the ash collection tank, which as filling is released. Ash is taken to the landfill as safe waste according to the 4th class of danger.
