residual oil fired steam boiler

Construction of gas residual fired steam boiler steam requirements for the construction of a gas boiler requirements, gas steam boiler installation for the construction of the boiler room have certain requirements, must comply with national requirements in the construction process. Gas and steam 1, the construction of a gas steam boiler room requirements 1) boiler room must comply with the "boiler energy saving technical supervision and management regulations" and "industrial boiler room design specifications" requirement. Gas steam 2) boiler room should have sufficient light and good ventilation, have the necessary antifreeze measures. And boiler room should stay away from schools, housing and densely populated areas. 3) the position should be close to the boiler room heating equipment, in order to reduce head losses and heat loss from the hot oil piping circulating pump. 2, furnace heat carrier device is arranged in claim 1) the sump should be lower than the lowest position of the heat carrier furnace and heat system 1 m, in order to put the net organic heat boilers and systems, sump and furnace heat carrier spacing less than 5 m or separated by a partition wall. It should be fitted with a sump exhaust pipe, which exhaust pipe diameter should be large and specifications than the inflation tube. 2) position of the expansion tank should be higher than the other devices and the piping system, the system must be higher than the maximum bottom level 1.5 m. It should not be installed directly above any one boiler, organic heat carrier to prevent overflow cause a fire. 3) the sump vent pipe, expansion tank, should be connected to the outdoor safety. Can not be mounted on the vent pipe to the valve, to ensure that the tank, the expansion tank to atmosphere to ensure atmospheric pressure operation. 4) the high volume of the expansion tank should be greater than 1.3 times and all the organic heat carrier furnace heat the entire heating systems is at the operating temperature is increased due to thermal expansion of volume. 5) low volume tank furnace heat carrier to be less than 1.2 times the total amount of organic heat. 6) hot oil circulation pump should be at least four weeks for 0.5 m space, and the inspection to ensure the installation routine, the need for maintenance.

Biomass boiler case:

The animal feed plant has a seasonal operation, but a relatively consistent load profile. The peak load is for 850 kg/hour of saturated steam at 8 barg (~650 kW see Figure 3). There is a much smaller load required for longer periods for miscellaneous process steam. The load is currently supplied by a very old light fuel oil (LFO) boiler. The load profile here facilitates an almost complete switch from LFO to biomass. 96% of the steam requirement would be covered by a 650kW biomass boiler. A small oil boiler, or built-in oil burner in the biomass steam boiler would be required to meet the smaller steam loads which would not be met efficiently by the biomass boiler. A straight-forward moving grate boiler with fire-tube heat exchangers can be used. The range of suppliers of biomass steam boiler equipment is limited below 1MW thermal as economies of scale are diminished below this level – a 650 kW boiler costs almost the same as a 1MW boiler.

Improve the thermal efficiency of gas residual fired steam boiler, to reduce the scale of the heating surface regardless prevention, gas steam boiler after a long run, it will produce some more or less scale. Gas steam boiler in operation, the furnace will be a series of chemical and physical reactions, in use, will form a hard and dense scale on the heating surface, which will directly result in reduced heat transfer efficiency of the boiler; and by corrosive effects of scale, will lead to reduced water wall furnace heat absorption gas steam boilers, which reduces thermal efficiency, waste input costs. The need to clean up the scale there is little that the boiler is to make long-term stable operation down. Scale thermal conductivity of only one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, during use in order to maintain a constant output of the boiler, it is necessary to increase the temperature of the fire side. The outlet temperature of the furnace gas steam boiler is increased during the process, so that it will lose gas steam boiler is increased, so that effective heat transfer will reduce the equipment fouling in the water wall, so it is very likely It can cause water wall tube wall temperature increases lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will be exposed to the original metallic tube, reduced to fouling. Secondly, after ignition gas steam boiler, flue gas temperature of the furnace needed to observe changes and the main steam temperature; when the main steam pressure is on the rise, if the boiler ignition, the smoke temperature rise speed or does not rise significantly Pianman, immediately check the oil on fire the gun.

April 4, 2019 morning, Xi'an Beilin haze iron-fisted rule to organize the use of gas-fired boiler unit of area businesses, held a 2019 low nitrogen gas boiler renovation work Publicizing.

The meeting mainly to accelerate the transformation of low nitrogen gas boiler Beilin, the ecological environment Beilin Branch Office investigator, neighborhood offices iron-fisted rule haze Director; area involving boiler 2019 user units, boiler enterprises, related to the monitoring unit responsible comrades total of more than 180 participants. Ecological Environment Agency Beilin Branch Comrade security level currently in Xi'an ambient air quality situation, problems and countermeasures were presented. Ecological Environment Agency celebration party strongman rule Beilin Branch Office Director haze on the transformation of relevant documents and carry out propaganda premium policy interpretation. 2018 transformation of the user units China Qiyuan Engineering Design & Research Institute Co., Comrade Yang Ann introduced to transform the experience of last year. Finally, the ecological environment Beilin Branch Bureau researcher Liu made a concluding statement:
