large coal fired steam

Direct contact heat exchanger using water spray in direct contact with the flue gas for heat and mass transfer. This way high heat recovery rate while absorbing a large amount of harmful substances in the flue gas, however, in this embodiment the recovered acidic water quality, limited use, hot water generated in waste heat recovery in general is difficult to use civil heating large fired steam room, thus heating boiler room is generally not used in this way.

Premix combustion characteristics of the premix before the large fired steam unit module should have the starting conditions premix boiler module are: stable surface combustion, combustion efficiency; compact combustion, high-density flame; load turndown ratio up to 1: 7, high adaptability gas; lower combustion product discharge. Gas through the solenoid valve, the air passes through the venturi, at the blowing action of the fan, into the fan together. The two fan gas blown stir premix chamber, the premix chamber acts as a pressure balance. Through the above process, gas and air to achieve complete premix. Fully premixed gas, fuel gas and oxygen molecules in contact with a large surface area, the combustion reaction is likely to occur. Ignition, fast response, more complete combustion, gas release more complete chemical energy; and a low air excess factor, a small amount of surplus oxygen, less air pollutants produced by the combustion, the flue gas of small size, low heat losses. Premix module weather-compensated boiler, energy-efficient and comfortable. Gas boiler in the heating season outdoor temperature varies from month to month, the same day the outdoor temperature is different at different times of the heat demand of the building will vary widely. Smart central controller with an indoor temperature sensor and a water temperature sensor, real-time collection and heating the indoor ambient temperature signal, automatically calculates the optimum water temperature, and controlling the number of modules put into operation, while maintaining room temperature stability, saves fuel, significantly lower operating costs. Premix module boiler system independent circulation, reduce fouling, eliminating the need for post-maintenance costs. Premix boiler module long life, easy installation, low power consumption, convenient and flexible capacity expansion and other advantages, not only reflects the small size, low cost, energy-efficient features, but also to maximize the use from the early and late maintenance are saving input costs and operating costs.

On the ISH heating HVAC industry event, fast Boiler bring new products customized for the paper and packaging industry well-built --- Euromonitor θ5 stunning debut, attracting various participants competing concerns. The product closed condensate recovery system, temperature condensate directly into the large fired steam design, three-pass boiler with economizer + + structure air preheater for recycling heat from the high temperature condensed water source, the thermal efficiency of up to 95%, to save operating costs with immediate effect.

First, wet maintenance 1, generally applicable to the shutdown period not exceeding one month of maintenance. 2, shutdown after the stipulated time exhausted furnace water, scale, slag, ash clean and clear. 3. Close all manholes, hand holes, valves, etc., and the large fired steam is completely isolated. 4, the resist solution prepared by passing an alkaline demineralized water, boiler water was added per ton of sodium hydroxide Na (OH) 8kg ~ 10kg, plus or sodium carbonate (NaC03) 20kg, plus or sodium (Na2P03) 20kg. 5, with special care and pump the prepared alkaline solution into the boiler. 6, when the protection solution is injected into all the open valve to the qualified demineralized water filled boiler, until the water overflows from the air valve, and then closing the air valve and the supply valve to open a dedicated pump cycle, a uniform mixed solution. 7, during the entire maintenance, should be periodically maintained with Weihuo drying oven outer heating surface, periodically turn the pump cycle, the concentration of the solution was consistent throughout, but also regularly take the solution assay and the replenishment solution, the PH value of the solution was ~ 10 between 12 to ensure that the alkalinity boiler water. 8, in the winter to take appropriate measures freezing. Second, the maintenance of a dry, apply a long shutdown period, usually for more than a month, especially in summer to disable heating and hot water boiler. 2, after the shutdown, the boiler water exhausted, clearly soot scale furnace, and the heating surface of the slag. 3, the choice of an appropriate amount of drying agent: anhydrous calcium chloride and commonly used desiccant quicklime. 4, off the boiler supply pipe, water supply, the valve on the outfall, or blocked by the separator Yan, completely isolated from the other operation of the boiler. 5, open manhole, hand hole, the boiler naturally dried if wet boiler, and with a slow fire the boiler furnace wall flue drying. 6, the boiler drying, the tray containing a desiccant into the furnace and the steam drum to absorb moisture, not in direct contact with the desiccant required boiler heating surface. 7, desiccant should be placed once, to see whether the heating surface corrosion regular weekly inspection of the boiler month, the timely replacement of the desiccant failure, a month later inspected once every two weeks.
