How to buy a hot water how to operate boiler management system tonnage and number of units to choose: Tonnage and epitope boiler should ensure the safety and reliability of the boiler room heating. When the boiler to stop using and overhaul, other boiler still meet the minimum daily minimum continuous production and heat demand. Therefore, the number of boiler room boiler generally not less than two. Only when all heating boiler room, no great impact on the thermal thermal equipment used by the user, in order to consider installing the boiler. Determine the tonnage and the number of boiler station, help save human, material and financial input. Thus, the tonnage of the boiler room of a single boiler to be larger, the number of boiler should generally be 3 or 4. For heating boilers and variety of rotating machinery driven by steam boiler, and the boiler to be expanded, the tonnage single boiler can be selected larger, the total number of small boilers. Strong hot water boiler tonnage and the number of user stations adapted to thermal load variations. Able to adapt to changes in diurnal and seasonal changes in heat users, the flexibility to adjust the operating conditions and the number of runs, the boiler is running properly in economic load.
Key condensing gas how to operate boiler management system condensing boiler key point is that condensing technology, is a new energy-saving, environmentally friendly technology; in fact, the principle is not complicated, simple generalization is the flue gas heat recovery through flue gas condensation. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, or even higher, so that water produced during combustion of the fuel (e.g. natural gas: CH4 + 2O2 → CO2 + 2H2O) is in a state of steam superheater in the flue gas, with the smoke. the loss of gas from the chimney. Traditional boiler thermal efficiency is generally only 85% to 91%. The Henan fast condensing gas boiler side, that the exhaust gas temperature is reduced to 35-60 deg.] C, sufficiently recovered latent heat of condensation and sensible heat in the flue gas water vapor, maximum thermal efficiency of up to 108.9%.
Fuxin City, Liaoning Province, Liaoning provincial government to respond positively to national policies according to the latest requirements, increase the intensity of atmospheric pollutants have increased in terms of the number of personnel or subsidies. Now funds raised 24.08 million yuan to support the removal of loose coal and coal-fired how to operate boiler management system control project.
According to statistics, since the fall of 2017, a total removal of Fuxin coal-fired boilers 488 units, a total of 1020.085 tons of steam, subsidies for 21.08 million yuan. At the same time, actively carry out the bulk coal Fuxin treatment project, the replacement of energy-saving small boilers 2,000 subsidy capital of 300 million yuan.
And, Fuxin City, developed a series of measures to scrutiny. To strengthen the management of special funds to ensure the flow of funds security, Fuxin City, the boiler license, inspection report and environmental impact assessment procedures to establish a furnace of a file basic information, to complete the formalities boiler users comply with the removal of subsidies standards, timely payment of subsidies to users hands.
After the implementation of removal of loose coal and coal-fired boiler control project implementation, Fuxin City air quality of the environment and the urban fringe have been greatly improved. According to the survey, this year, the average concentration of PM2.5 Fuxin City 35 micrograms / cubic meter, improved 12.5% year on year; PM10 average concentration of 67 micrograms / cubic meter, improved 17.8% year on year; air quality compliance rate of 81.6%, an increase of 4 %.
What are the characteristics of the how to operate boiler management system? 1, the automatic control of the boiler pressure controller, tracking, on the feed pump may be electrically heated tube automatic start and stop control when the load changes, may be manually controlled. With a number of complete protection, leakage protection, water protection, ground fault protection, overcurrent protection, what are the characteristics? Boiler automatic protection, safe home. 2, automatic intelligent control techniques, without staff on duty. Flexible work can be set to manual or automatic mode. There are 3 boiler, automatic operation may be set as required boiler period, one day may be provided a plurality of different working periods, so that each heating boiler starts automatically sharing group, the group switching cycle heating, the respective contact time, the same frequency improve equipment life.

Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.

Nearly all fuel burners use a common drive motor that is connected to the driven devices such as valves and damper with linkage rods. They work fine but they dont work as well as they could. The efficiency of a modulating burner system is maximized by keeping the air to fuel ratio to a minimum to ensure complete combustion, across the firing rate, as the heating load changes.

A burner management system is responsible for the safe start-up, operation and shutdown of a boiler. It monitors and controls igniters and main burners; utilizes flame scanners to detect and discriminate between the igniter and main flames; employs safety shut-off valves, pressure, temperature, flow and valve position limit switches and uses blowers to cool the scanners and/or provide combustion air for the igniters.
