Steam Boilers for power generating units with sub-critical steam conditions, capacity of up to 660 МW and production from 50 to 2000 tons per hour
«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, «Krasny Kotelshchik» 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. «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.
Today, newly designed boilers under the «Krasny Kotelshchik» brand are high technology boiler units equipped with highly efficient burner devices demonstrating technical economic and environmental indicators of world level.
The year 2003 witnessed the commissioning of a drum boiler with maximum level of parameters for boilers with subcritical steam conditions and with output steam pressure of 18 МPа.
Steam drum boilers under the TKZ brand currently represent a broad product range. They successfully operate on various types of fuel: various types of coals, natural gas, blast furnace gas, middlings, peat, furnace oil, etc. on power generating units with subcritical steam conditions.
«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.
