Boilers for burning different types of bio mass (wood chips, straw pellets, husks) with different production
«Krasny Kotelshchik» being the historically recognized leader in the area of boiler unit manufacture for electric power generation, gives special attention to reliability, efficiency and durability of the equipment manufactured. The company has all the necessary competencies in creation of power generating steam boilers, drum boilers and once-through boilers, with production from 50 to 3 950 tons of steam per hour, rated for an operating pressure of up to 28 МPа and more, for operation on all the types of energy fuel (anthracite, brown coals, bitumen coals and lean coals; coke gas, blast furnace gas and natural gas; oil, furnace oil, etc.). Steam boilers are designed by the company’s engineering divisions, which possess extensive experience and successful track record in development and research.
The production facilities of «Krasny Kotelshchik» are capable of making up to 4 GW worth of boiler equipment per year. Throughout several recent decades, TKZ has been the leading supplier of once-through boilers for power generating units of 1200, 800, 600, 300 МW rated for supercritical steam pressure for powerful thermal electric power plants in Russia and in the world. In terms of the key reliability and economy indicators, these boilers correspond to the modern level of international boiler manufacturing by foremost boiler producers, which is proven by many years of their service. The Taganrog Boiler-Making Works «Krasny Kotelshchik» is one of the world’s leaders in total output of supercritical pressure boilers for power generating units of 1200, 800, 600 and 300 МW.
Steam Boilers Е-40-2,25-305ОR (model ТОЕ-040) are drum boilers with natural circulation. Key parameters are as follows:
— production of 40 tons/hr
— superheated steam pressure of 2.25 МPа
— superheated steam temperature of 305°С
Implemented in such boilers is the technology of grate firing on a cooled grate. Fuel is production wastes of the plywood combine.
Boilers of «Krasny Kotelshchik» for burning bio mass allow solution of a number of issues:
— utilization of production wastes in order to reduce or completely eliminate dependence on outside energy sources;
— satisfying the existing need for heat of the industrial facilities and their users;
— covering, partially or completely, the need for electric power of industrial operations.
The boilers comply with the up to date reliability, economy and environment control requirements.
«Krasny Kotelshchik» provides a package of installation supervision services, startup and adjustment supervision services, testing services to commission boiler and boiler related auxiliary equipment, upgrading services, repair and rebuilding operations, supply of spare parts and special materials as well as performs an all-round retooling of the boiler island resulting in an increase in productivity, efficiency factor of the boiler unit and reduction in discharges.
Services provided by our company include technical supervision of installation, startup and adjustment operations, commissioning into operation of the power generating equipment, as well as warranty service, participation in planned repairs, engineering support of repairs, development of repair technologies, training customer personnel, their contractors, consulting services and post-warranty service support. We are willing to provide solutions to upgrade other manufacturers’ boilers, basing ourselves on the customer’s wishes and existing experience in upgrading and remodeling.
- Implementation of the process measures aimed at reducing nitrogen oxide discharges (use of multi-stage fuel combustion circuits, new low toxicity burners, recirculation, etc.).
- Use of hard slag removal when bitumen coals are burnt in order to reduce nitrogen oxide discharges.
- Upgrade of boiler unit components:
— reconstruction of furnace walls (replacement of furnace walls with gas tight/all welded furnace walls);
— modification of furnace and burner devices as well as organization of three stage fuel burning (reburning process) using natural gas as reducing fuel;
— use of selective non-catalyst method of NОx suppression to achieve normative NOx concentration values;
— reconstruction of the dust preparation system and high concentration dust supply system;
— reconstruction of dust, gas and air ducts.
- Reconstruction of gas and furnace oil boilers ТGМP-314 and ТGМP-344 with an add-on of a combustion turbine unit of gas-turbine plant (combustion turbine unit with discharge of gases from the gas turbine into the boiler).
- Replacement with upgraded boilers (ТP-80, ТP-87 with ТP-87М; ТP-170 with TP170М; ТP-230 with ТP-230М; ТGМ-84 with ТGМ-84М), designed to replace the boilers which have reached the end of their service life while retaining, subject to diagnostics results, the foundation, boiler carcass and drum.
- Boiler upgrade (ТP-216М, ТP-100М, ТPP-110М, PК-33М, P-50 and P-50М, P-57-R and P-57-R, BKZ 640-140 PТ М ) depending on the type in order to:
— increase energy efficiency (increase efficiency factor);
— raise the temperature of the main steam;
— increase the boiler production;
— reduce NОx discharges;
— reduce discharges of hard particulates;
— achieve up to date SOx concentration indicators;
— stop using auxiliary fuel within the load range between 100-70 Dnom;
— reduce air infiltration.
- Modernization of gas air heater seals for greater reduction in the level of air flows.
