Down below there is a block diagram of basic unit for standard boiler house, which can provide heating and hot water supply to the consumers. The unit consists of two steam boilers of DKVr 6,5 - 13 GM (De 6,5 - 14 GM) type with economizers as well as traditional equipment of following main systems: the system of continuous bleeding for steam upper drums; system of chemical treatment of natural water, feed water and delivery water; system of heating and hot water supply to the consumers together with delivery equipment; system of air sup-ply to boiler furnaces and extraction of combustion products to the air.

The traditional auxiliary equipment, which is shown with yellow colour in the figure above, is advisably to be replaced with principally new equipment based on transonic jet technologies (Fisonic technologies) using transonic jet apparatus (TJAs) under complete usage of boiler house design capacities.

• The system of continuous bleeding for steam upper drums. The continuous bleeding separating unit, cooling heat exchanger and bubbler - their total dry weight is about 1.5 tons – are to be replaced with TJAs, which 100% utilize bleed water and heat, the weight of TJAs is about 20 kg. Also TJAs absolutely do not contaminate the environment with heat or chemical products and do not need any supply of pure water for dilution of bleed water before emission to sewage system.
• The system of chemical treatment of natural water. The heat exchangers (incremental heating of natural water, boiler's feed water cooling, heating of chemically treated water), de-aeration plants (feed water and delivery water), pumps (natural, chemically treated and delivery water), which total dry weight is about 7 tons, are to be replaced with TJAs – heat exchangers, circulation pumps and generators of additional heat from water (all these activities are covered simultaneously by every device!) and TJAs – de-aerators of feed water and delivery water. Total mass of equipment set is not more than 200 kg.
• The system of heating and hot water supply. Delivery heat exchangers, delivery and charging pumps, storage tank and condensate collector, their total dry weight is about 10.2 tons, are to be replaced with TJAs – heat exchangers, circulation pumps and generators of additional heat from water (all these activities are covered simultaneously by every device!). TJA set for heating facilities is not more than 150 kg. There is only one storage tank of 10 m³ capacity and dry weight about 3.2 tons remained in the system, which can carry out the functions of all remote tanks and it avoids contact of transfer fluid, water, with ambient air.
• The system of boiler fumes extraction and their heat utilization. Economizers, exhausters, gas-mains and chimney (metal one for this case) of total dry weight about 22.6 tons are to be replaced with TJAs – heat exchangers with effect of generation of additional heat from water and cleaning of boiler fumes, and cyclones, which are to dry out the gases emitted to the atmosphere and are to feed hot water to heat exchangers of hot water supply system. Total dry weight of equipment set is about 900 kg.

The installation of TJA instead of standard traditional equipment will lead to decrease of production area (which are necessary to suit TJA) 2 times minimum, and design of new boiler house using Fisonic technologies can reduce drastically capital investments for erection of production facilities.

The capital investments. The total price of replaces traditional equipment is about 3.1 million rubles. In accordance with current practice of construction engineering for installation of traditional equipment in turn-key project the capital investments (without considering cost of monitoring systems and control automation) are double purchase price of equipment, or С_citr ≈ 6.2 million rubles. Total capital investments for turn-key project with installation of TJAs together with set of supporting equipment is about 0.7 С_citr or С_ciTJA ≈ 4.3 million rubles.

The principal value of offered equipment is not only in 30 % reducing of non-recurring capital investments, but in much more resultant (comparing to traditional equipment) reduction of constantly rise of operating costs. The rise of operating costs is specified by continuous rise of electricity and fuel rates as well as rise of operating personnel salary.

The operating costs. The use of brand new Fisonic technologies leads to resultant reduction of operating costs, because of the following factors:

1. power consumption reduces because of excluding of some devices of electrical equipment;
2. heat leakage to environment reduces because of excluding of some devices of heat equipment;
3. maintenance costs reduce because of excluding of some devices of electrical and heat equipment, and installed TJAs have got 2 - 3 times longer maintenance periods and the scope of maintenance is much less;
4. additional energy (above input energy) is generated as a result of better usage of water internal energy, and some part of it is a natural fuel.

All indicated above activities, using together, help: to reduce the electric power requirements in generation of heat energy, the reduction can be up to 80 % of consumed load of traditional equipment, to reduce the fuel consumption by 50 % with the same connected load or double increase the connected load with the same generation power.

As a result, the rebuilding capital cost payback periods reduce at upgraded boiler houses (in several times, comparing to the ones with upgrading of traditional equipment), it is especially well seen in replacing of expensive equipment of foreign origin. The self-cost of produced heat energy reduces both for upgrading and newly constructed boiler houses.

For housing and utilities infrastructure the last mentioned factor leads to reduction of budgetary expenditures for heat supply and also, it is even more important, it helps to reduce customer charges for supplied heat even in case of electricity and fuel rates growth and cuts down the social stress of housing and utilities reform.
