how to build a hot water boiler

Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of ​​tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast boiler steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .

Waste heat recovery boiler applications:

Traditionally, waste heat of low temperature range (0-120 °C, or typically under 100 °C) has not been used for electricity generation despite efforts, mainly because the waste heat boiler efficiency is rather low (max. 18% for 90 °C heating and 20 °C cooling, minus losses, typically ending up with 5-7% net electricity). In general, waste heat below 100 °C could be used for the production of bio-fuel by growing of algae farms or could be used in greenhouses or even used in Eco-industrial parks.Waste Heat of medium (120-650 °C) and high (>650 °C) temperature could be used for the generation of electricity or mechanical work via different capturing processes.

Electric steam boiler before the operation using the operating electric steam boiler 1. The apparatus used should be turned off drain valve, supply valve, inlet valve open, check the power supply is normal. 2. When the controller stops the alarm by pressing the power switch, the switch to Ⅲ heating profile, alarm controller (due to lack of water in the boiler), while the indicator light replenishment pump starts to operate, to pay low water levels, a high level continues automatic replenishment , water pumps stop, boiler heating lamp is lit, the boiler automatically start heating. 3. When the boiler pressure reaches the set value, the heating switch to Ⅱ, this time to turn the steam valve, the use of steam. 4. When using steam, the furnace pressure drop, when the pressure dropped to the lower limit set value, the heating boiler starts automatically. 5. When steam is used, oven declining water level when the water level falls below the low, i.e. start the pump, a high level of replenishment to the furnace, the boiler heating cycle automatically. When the water level is below the low water level, and supply system is not working properly, after 10 seconds the water level does not reach the low water level electrode, the controller continuously alarm and shutdown protection. 6. Use process to maintain the boiler pressure at about 0.4Mpa, if necessary, by heating the toggle switch adjustment. 7. The use of the process, such as more than 15 seconds duration alarm alarm, should immediately check off the soft water tank is normal. 8. The work is completed, press the power switch off the power, power light is off.

Common methods of water quality testing methods commonly used in industrial boilers which industrial boiler water quality testing of water quality testing methods which are commonly used in industrial boilers which (1) comparative analysis. Industrial boiler water quality testing will generally take two comparative analysis. The first analysis method is to compare room. Indoor contrast mainly through the contrast between the contrast between people or equipment. The second method is to compare the laboratory analysis. This method is mainly for comparison and testing personnel random error, system error. (2) review sample. Water quality sampling, number, checking and retention, and then returned to retest samples deputy members. Deputy sample prior review, to be processed. Environment and pay attention to time during retest retest sample, so that the processing result can be obtained twice, and then the results were compared. Sample analysis (3) in parallel. When parallel samples for monitoring, to ensure that each batch of samples will be monitored. Determining the actual number of replicates the number of samples so that it can effectively ensure that the number of replicates measured more reasonable. Also setting it within a reasonable range. (4) control a calibration curve method. The calibration curve using the control method can make the results more accurate. First, the calibration curve Control Act mainly a combination of a certain time period, so that the result will be more timely and effective, precise terms, generally to a calibration curve based on monitoring of time each batch of samples. Second, to ensure the accuracy of the calibration curve, it can really play to monitor the effect of the sample.
