Boilers Typical modern boilers in the South African sugar industry produce superheated steam at a pressure of 3100 kPa (abs) and a temperature of 400°C. They are designed to burn bagasse, coal or a mixture thereof and are equipped with a full heat recovery system. Boiler configuration The main components of a modern boiler are: the grate, fuel feeders, combustion chamber or furnace, water or mud drum, steam drum, main bank, superheater, economiser, air-heater, scrubber, induced draught (ID) fan, forced draught (FD) fan, secondary air (SA) fan, boiler feed water pumps and some auxiliary equipment
A strict boiler installation access. For newly installed boiler strictly enforce provincial and municipal environmental policy, a full cessation of 35 tons and below, installation and construction of coal-fired boilers to inform, installation supervision, inspection and use of registration, to cooperate with the elimination (dismantling) work.
Second, the coal-fired boiler using a registration certificate cancellation notice. According to regulations, the original registration for the 83 and 10-ton coal-fired boilers using the write-off registration certificate shall be published on the government website, while informing the inspection unit will not be tested.
Third, strengthen supervision and law enforcement boiler safety, to promote the phase-out of coal-fired boilers. The boiler safety supervision and law enforcement with prevention and control of air pollution combine to crack down on illegal installation of boilers, illegal use, not extended inspection, not extended rectification risks and other illegal acts, to perform their duties according to law, to promote the phase-out of coal-fired boilers smoothly. This year we have gone through all kinds of boilers 117 units, of the 10 units are still using coal-fired boiler inspection found, ordered to stop using and timely communicated to the relevant environmental authorities and the town street, cooperate with the 10 coal-fired the dismantling of the boiler.
The difference with other similar electric boiler heaters at 1, what are the advantages compared with the radiant heater (little sun)? (1) life better than radiant heaters. Since the radiant heater as an ordinary electric wire electric wire and exposed in the air, thus greatly reducing its service life, can not be compared with the life of our heaters. (2) better than the radiant heater. Radiant heater use will emit visible light at night can affect people's sleep. Our heater does not have this problem. Uneven heating radiant heater, heating only locally, poor comfort. Our natural convection heater, heat evenly and comfortable. (3) secure than radiant heater. Radiant heater exposed electric wire, when used in a humid environment, the risk of leakage easily occurs. Children while playing as a foreign object is inserted into the radiant heater, it is very dangerous. Our heater level of protection is IP24, can be used in bathrooms and other damp environment, security is very high. Wide range (4) applies, appearance can be used in homes, offices, schools, shopping malls, hotels and other places. 2, compared with geothermal cable What are the advantages? (1) The first is the low energy consumption. Geothermal heating cable to put the entire floor, the floor itself to large amounts of heat loss, and also a part of the heat to the ground or downstairs, wasted a lot of power. (2) The second advantage is that the heat faster. Electric heating can be substantially open desired temperature is reached twenty to thirty minutes within a room, and geothermal cable to at least three to four hours using far less flexibility heater. (3) The third is the construction convenient, easy maintenance and low installation costs. Our simple heater installed as long as there is a wall socket and switch can be used, and geothermal cable construction maintenance is extremely complex and expensive.
